How do you simpilfy radicals?

Answer 1

Two general rules are:1. Not to have a perfect square as a factor within a square root (or perfect cube for cubic roots, etc.) Split it off. Example: root(12) = root(4) x root(3) = 2 x root(3)

2. Often, people try to avoid square roots in the denominator. Example: 1 / root(2). Multiply top and bottom by root(2), to get: root(2) / 2.
