Question

Plz answer . I would highly appreciate it thanks

Answer 1

I got 324 because as you have a negative integer you would have to switch it into a fraction and by multiplying 9 *9 it’ll be 81. So then it’s 81 * 1/4 = 324

Answer 2

9x^2y^(-2) x=-3 y=2
= 9(-3)^2(2)^-2
=9(9)(0.25)
=20.25
=20 1/4
so the answer is the 3rd one.
