In this lesson, we learn how to simplify a rational expression with an imaginary root as the denominator. The instructor shows us how to rewrite negative roots to avoid having negative numbers under the square root. They also explain how to handle imaginary numbers, including multiplying by i to eliminate it from the denominator. Overall, it is a helpful guide for simplifying complex expressions involving imaginary numbers.

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.
