Hi Andrew;

9h^{-2}*5h^{10}

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

-2+10=8

This is h^{8}

9h^{8}*5

45h^{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)}
