Solving Exponential Equation with Fractional Base
In this lesson, we learn how to solve exponential equations with a fractional base. The key is to get rid of the fraction and use the rule that x to the negative first equals one over x. By rewriting the equation without fractions and using the one to one property, we can solve for x with ease. Remember to avoid dealing with fractions to make the problem simpler.
Solve an exponential equation when your base is a fraction
I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
