Hi Andrew;

9h

^{-2}*5h^{10}First, let's consider h

^{-2}* h^{10}-2+10=8

This is h

^{8}9h

^{8}*545h

^{8}The Ruie is when you have two similar numbers (same base), each raised to a power, the product of these (base) numbers raised to their power is the base raised to the sum of e powers.

i.e. (a

^{x})*(a^{y}) = a^{(x+y)}
