## Intro to Rationalizing the Denominator
If you can't express the denominator of a fraction in the form of a/b, where a and b are integers, then the denominator is irrational. To simplify the fraction we should rationalize the denominator. Rationalizing the denominator can aid you in solving certain equations. There are a couple ways to do this.

### Multiplying by a Root
We can multiply the top and bottom by a root. Notice that we are multiplying the fraction by root 2 divided by itself which is just another way or writing 1.
