Multiplying & Dividing

Sometimes it is desirable to find an equivalent radical expression that does not contain radicals in the denominator. This process is called rationalizing the denominator. The goal is to make sure there are no radicals left in the denominator of the fraction. In order to do this, multiply the fraction by a fraction equal to one.
