Lesson Summary:

In this lesson, the instructor explains how to simplify expressions by rationalizing the denominator. They demonstrate how to get rid of a radical to make it easier to work with, using the example of 4 divided by the square root of 3. They show that you can multiply the radical with itself to remove it and provide multiple ways of expressing the simplified answer.

Lesson Description:

Here I show how to simplify an expression.

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.
