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}

How to solve 7 2/6 + 8 5/6
natima [27]
Separate them first.
7+8=15
5/6+2/6=7/6
There can't be 7/6, so it becomes 1 and 1/6,
15+1+1/6=16 1/6
The answer is 16 1/6.
