Use this rule of exponents: $x^color(red)(a) xx x^color(blue)(b) = x^(color(red)(a) + color(blue)(b))$

$9^color(red)(4) * 9^color(blue)(5) = 9^(color(red)(4) + color(blue)(5)) = 9^9$

$9^9$

When finding the product that contains indices, since it has the same base you simply add the indices together.

That is the multiplication law of indices.

$9^(4+5)$ = $9^9$
