      Square roots are the reverse operation of squaring a value. Numbers whose square roots are Integers are called perfect squares. For example: 4=2, so 4 is a perfect square. The square root symbol ( ) is called a radical. You can use a calculator to determine the approximate value of a square root or simplify square roots, as shown below:
