Sarah told Tanya that the numbers in the right column double each time as you go up. Explain why they are double by writing
, and as products of ’s.
On your own paper, copy the table and fill in the values for
What happens to the values in the right column as we go down from
They are reduced by half.
In order to make the rules of exponents in base
