## How Do You Rationalize a Denominator?

Removing Radicals from the Denominator For an answer to be in proper format, radicals (square roots) cannot be left in the denominator. The way to remove them from the denominator is to ## How to Rationalize the Denominator

The denominator here contains a radical, but that radical is part of a larger expression. To get rid of it, I'll multiply by the conjugate in order to simplify this expression. The multiplication of the ## Rationalizing Denominators

To rationalize a radical in the denominator means to take the given fraction and multiply it by the radical rewritten as a factor of one. Multiplying the radical as a factor of one means to ## How to Rationalize a Radical Out of a Denominator
