Lesson Summary:

In this lesson, you will learn how to simplify expressions that have imaginary numbers in the denominator. The key to simplifying these expressions is to recognize that i is equal to the square root of negative one. To get rid of i on the bottom, you'll need to multiply the numerator and denominator by i. Simplifying the expression after that involves some basic algebraic manipulation and recognizing that i squared is equal to negative one.

Simplifying when you have imaginary numbers as your denominator

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.
