Answer 1

Answer:

$9^{-7}, 9^{-2}$

Step-by-step explanation:

$\frac{9^5\times9^{-9}}{9^3}\\\frac{9^{-4}}{9^3}\\ 9^{-7}$

When you multiply like terms, you add their powers. When dividing like terms, you subtract their powers (subtract the power in the denominator from the one in the numerator).

$(9^4)^3\times9^{-14}\\9^{12}\times9^{-14}\\9^{-2}$
