Worksheet Overview

When we raise a number which is less than 1 to a given power, the answer is smaller than the original number.



Work out (0.02)4



We must calculate 0.02 x 0.02 x 0.02 x 0.02


We know that 2 x 2 x 2 x 2 = 16

But now we must divide each of the 2s by 100

and therefore we must divide the 16 by 100000000.


16 ÷ 100000000 = 0.00000016


So  0.024 = 0.00000016


Similarly  0.23 = 0.008 and 0.043 = 0.000064
