How to simplify the square root of an expression by using perfect squares

The video tutorial explains how to simplify radical expressions by identifying perfect squares and rewriting terms using their largest square numbers. It begins with an introduction to square roots and perfect squares, followed by examples of perfect squares. The tutorial then demonstrates how to simplify expressions by breaking down numbers and variables into their largest square components, ultimately simplifying the radical expression.

What is the main purpose of taking the square root of a number?
