A square root is the opposite of squaring a number. The symbol for square root is  √.

So if 3²=9 then  √9=3

A cube root is the opposite of cubing a number. The symbol for cube root is ³ √.

So if 3³=27 then ³ √27=3

To square a number you multiply it by itself. For example 3² =3×3=9

To cube a number you multiply it by itself three times. So 3³=3x3x3=27

This exercise will help you do that-don’t be tempted to use a calculator! For Functional Skills students you can use a calculator. Look for the x² and x³ buttons on your scientific calculator and use these.
