This document provides an overview of simplifying radicals. It defines key terms like radical, radicand, and index/root. Perfect squares are explained as numbers that are the square of a whole number, like 4 = 2^2, and taking the square root of a perfect square gives one of the dimensions of the square. The method for simplifying radicals is described as completely factoring the radicand and matching pairs of the same factor to simplify inside and outside the radical. Examples of simplifying different radicals are provided.
