## Rational Exponents and Radical Form

This video math lesson introduces the connection between radical form and rational exponents. The first example establishes the connection between the index and the denominator. It models evaluation three real number expressions.

The definition of Rational Exponents in Radical Form is explored and example two should help in reinforcing the fact that the numerator is determines the power and the denominator determines the index.

Example 3 is a word problem. As many of my students in class complained or should I say, voiced their concern over covering a word problem. It is just an application of a known equation with two variables. You have to two things

1. Identify what you must find
2. Identify what you are given

Once you do that it is quite easy. You will see in the video. Enjoy.

1. Mr Pi,

Excellent video. Keep it up.

• Guillermo,

Thank you very much. I have been putting so much time into my classroom, I do not have the time to blog about math like I want to.

Mr. Pi
