Many numbers do not have a whole number as a square root. To find the square root of a large number, you can use a calculator.

Press the square root key and then the number. Press enter to display the square root answer.

If you use a calculator to find the square root of a number that is not a perfect square, the answer will have a decimal part.

If you don’t have a calculator, you can estimate the square root of a number by comparing it to the square roots you do know.
