#### Worksheet Overview

This activity is about squares and square roots.

We're going to practise using a calculator and finding the square button (x2 ) and the square root button (√)

Example 1

Using the  x2 button, find 162

First, put in 16, then x2, and finally =

Example 2

Using  the (√) button, find the square root of  596 or  √596

First, tap the √ button, then 596, and finally =

The answer is 24.4 to one decimal place.
