When we raise a number which is less than 1 to a given power, the answer is smaller than the original number.
Example
Work out (0.02)4
Answer
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
