This worksheet is about working out powers in your head.
Write down the following without using a calculator.
Check your answers on your calculator.
Keep practising those you did not know until you know them all by heart.
any number raised to the power 0 is 1
when you raise a number to the power ½, you are finding the positive square root of the number
when you raise a number to the power 1/3, you are finding the cube root of the number
this is cubing the number, i.e. 10 x 10 x 10
