Answer:
1/9^5
Step-by-step explanation:
9^2 / 9^7
We know that a^b / a^c = a^(b-c)
9^2 / 9^7 = 9^(2-7) = 9^-5
But we don't like negatives in the exponents
We know that a^-b = 1/ a^b
9^-5 = 1/9^5
[tex] \frac{ {9}^{2} }{ {9}^{7} } \\ = {9}^{ - 5 } = \frac{1}{ {9}^{5} } [/tex]
yes, the last answer is correct....
