In this module we will take a look at methods for simplifying radicals.  Remember:  in mathematics, we are commonly interested in the exact answer.  Whenever we round decimals, we are approximating the number.  If our answer contains a square root of a number that is not a perfect square, the number is irrational, meaning it is decimal that is non-terminating and non-repeating.  To maintain its exact value, we need to present the number as a radical (root).  Of course, we want it simplified.  We call this Simplest Radical Form.
