In this lesson, we learn how to simplify rational expressions by using properties of exponents. Dividing two exponents is as simple as subtracting one from the other. Additionally, x divided by x equals one, and x to the first power is the same as the single x. By applying these rules, we can simplify expressions like negative seven w to the seventh divided by six w to the fourth to negative seven divided by six w to the third.
Simplify a rational expression by using properites of exponents
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.
