Analysis of the Solution

Using laws of logs, we can also write this answer in the form t=\mathrm\sqrt. If we want a decimal approximation of the answer, then we use a calculator.

Example: Solving Exponential Functions In Quadratic Form

Solve ^-^=56.

\begin^-^=56\hfill \\ ^-^-56=0\hfill & \text.\hfill \\ \left\left=0\hfill & \text.\hfill \\ ^+7=0\text^-8=0 & \text.\hfill \\ ^=-7}^=8\hfill & \text.\hfill \\ ^=8\hfill & \text.\hfill \\ x=\mathrm8\hfill & \text.\hfill \end

Analysis of the Solution

When we plan to use factoring to solve a problem, we always get zero on one side of the equation because zero has the unique property that when a product is zero, one or both of the factors must be zero. We reject the equation ^=-7 because a positive number never equals a negative number. The solution x=\mathrm\left is not a real number and in the real number system, this solution is rejected as an extraneous solution.

Examples Of How To Solve Exponential Equations Without Logarithms

Example 1: Solve the exponential equation below using the Basic Properties of Exponents.

Solution:

  • Given
  • Express the denominator of the right side with a base of 5. We have 125 = .

Apply the Negative Exponent Property.

  • At this point, the bases are the same therefore set the powers equal to each other.
  • This is just a simple one-step linear equation.
  • To solve for x, divide both sides by 3. Thats it!

The final answer here is x = – 1.

Example 2: Solve the exponential equation below using the Basic Properties of Exponents.

Solution:

  • Given
  • Express all numbers with the base of 2. So we have: 8 = and 256 = .

Apply the Product Rule on the left, while using the Power to a Power Rule on the right side.

  • Here we are ready to set the powers equal to each other since we are able to create single bases that are the same on both sides.
  • Solve the simple linear equation.
  • Subtract both sides by 7xto isolate x. Done!

The final answer is x=3.

Example 3: Solve the exponential equation below using the Basic Properties of Exponents.

Solution:

  • Express each number with a base of 2. In doing so

64 = and 16 =

  • Applying Power to a Power Rule.

In other words, multiply the inner exponent to the outer exponent. Do it for both the numerator and denominator.

  • Apply the Quotient Rule.

Subtract the top exponent by the bottom exponent.

  • This is how it looks after subtracting the exponents.

Now, looking at the right side, can we express 1 as an exponential number with base 2?

The final answer is x = 3.

Will I Really Need Algebra In Real Life

Sadly, we cannot answer that question for you. Its not a simple yes-or-no situation.

Think of the rate of non-traditional students retaking math classes, and all the old people returning to uni after years of dropping out, even though they dont need algebra for their jobs.

The very fact that they are studying algebra all these years after high school highly indicates that they havent used algebra a lot since the time they finished their studies. They made it this far without needing algebra, but here they are returning back to the very college seats they abandoned years ago because they felt the necessity of such a subject.

Take into consideration that you didnt learn the alphabet back in kindergarten because you knew youd be studying Shakespeares plays this year. The same goes for algebra you dont study it because you know that youll be interpreting graphs and working with quadratics in a few years, you study it to build the cornerstone for bigger things to come, and to help create better opportunities for yourself in the future.

Algebra is the key to various domains no matter how big or small they are.

For instance, lets assume that your job requires working with spreadsheets filled with formulas. For that, you need a basic understanding and enough knowledge of variables and equations.

How Relevant Will Algebra Be In The Years To Come

Its undeniable that jobs will require different skill-sets in twenty or thirty years from now, but the only thing thatll remain constant is mathematics. One plus one will always equal two.

Sure, youll receive the required training for any job youll get, but you still need a decent knowledge and skillset to get that job in the first place. To be on pace with the progress, to remain on top of the ladder, and to open up for better future opportunities, you need the strong foundation that mathematics provides.

The lessons and patterns taught by mathematics are vital. Learning formulas and variables, interpreting graphs and tables, and thinking logically to find solutions are essential skills that will prove to be useful for the rest of your life. They are not things that you learn in school just to pass a test theyre an arsenal of capabilities that, if mastered, will yield great results for both your professional and personal life.

So, thats it those are the reasons why learning and studying algebra is essential no matter where you are in your educational ladder.

A Value Is Said To Be A Root Of A Polynomial If

College Algebra – Solving a Rational Exponent Equation Example 3

The largest exponent of appearing in is called the degree of . If has degree , then it is well known that there are roots, once one takes into account multiplicity. To understand what is meant by multiplicity, take, for example, . This polynomial is considered to have two roots, both equal to 3.

One learns about the “factor theorem,” typically in a second course on algebra, as a way to find all roots that are rational numbers. One also learns how to find roots of all quadratic polynomials, using square roots when necessary. There are more advanced formulas for expressing roots of cubic and quartic polynomials, and also a number of numeric methods for approximating roots of arbitrary polynomials. These use methods from complex analysis as well as sophisticated numerical algorithms, and indeed, this is an area of ongoing research and development.

Systems of linear equations are often solved using Gaussian elimination or related methods. This too is typically encountered in secondary or college math curricula. More advanced methods are needed to find roots of simultaneous systems of nonlinear equations. Similar remarks hold for working with systems of inequalities: the linear case can be handled using methods covered in linear algebra courses, whereas higher-degree polynomial systems typically require more sophisticated computational tools.

Rewriting Equations So All Powers Have The Same Base

Sometimes the common base for an exponential equation is not explicitly shown. In these cases we simply rewrite the terms in the equation as powers with a common base and solve using the one-to-one property.

For example, consider the equation 256=^. We can rewrite both sides of this equation as a power of 2. Then we apply the rules of exponents along with the one-to-one property to solve for x:

\begin256=^\hfill & \hfill \\ ^=^\right)}^\hfill & \text.\hfill \\ ^=^\hfill & \text.\hfill \\ 8=2x – 10\hfill & \text.\hfill \\ 18=2x\hfill & \text.\hfill \\ x=9\hfill & \text.\hfill \end

Studying Algebra Is Stupid

Have you ever asked yourself why do people always complain about math and science? Is it because they require a lot of discipline and dedication? Or because theyre difficult to understand?

Have you ever noticed that no one asks why you have to take physical education or English literature classes, even though math, physics, and science are much more critical to the founding of the modern society than Shakespeare or the techniques of shooting a three-pointer?

Education has to be fun, easy, and entertaining in order for it to be acceptable, or so says the modern American educationist philosophy.

Todays students believe that if a subject requires some effort, they shouldnt have to take it. Little do they know that the most beneficial things in life demand making some effort.

If you want an excellent job, an alluring career, a limitless future, youll most definitely be in need of some mathematical skills, and when you say math, you say algebra.

Have you ever thought about why do you hit the gym regularly? Is it because lifting weights is effortless? Or because you want to get better, challenge yourself, build your strength, and prepare your body for whatever you might encounter in life?

Why do people cycle or jog? Is it because its fun to sweat bullets and get knee soreness? If I were to guess I would say that they do it because they want to be healthy and strong in order to resist diseases and be ready for whatever health obstacle life may throw their way.

My Career Wont Require Algebra

One of the many differences between a college graduate and a trained employee is the students capability of a deeper understanding of the situation and a better ability to build links and connections and acquire new skills.

You certainly wont need everything you learned in algebra, but does this imply that you should drop out of your college and only get the training thats required for the job you seek to take?

Im sure your answer goes along the lines of I cant afford to drop out, I cant be qualified for that job without a college diploma or degree.

So, in order for you to get your dream job, you need to prove yourself and capabilities through a particular skill set, but to really display that proficiency, you need a college degree. To obtain that degree, you need algebra. Algebra, in other words, is a must if you want the job.

Math people have a common saying that goes along the lines of one truly learns arithmetic and pre-algebra in algebra and algebra and trigonometry in calculus. The meaning behind all of this is that one truly gets a better understanding of a specific material once they have to use it in different situations.

Take your algebra class, practice using our algebra simplify calculator, and youre bound to master those skills.
