Use a Calculator to Find Squares and Square Roots

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 (√)  

Round your answer to 1 decimal place where necessary.

Example 1

Using the  x² button, find 16² 

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

The answer is  256

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.

Let's give it a try! If you need to remind yourself of the order of the buttons, just click on the red button and you'll be able to see this introduction again.
