I'm not getting the answer choices

Evaluate 9x^2y^-2 for x = –3 and y = 2.

a 324
b 20 1/4
c 9(-6)^0
d 1/144

b 20 1/4

9*(-3)^2*(2)^(-2)................2^(-2) = 1/2^2

9* 9 * 1/4

81/4 and 4 goes into 81, 20 times with 1 left over giving 20 1/4

B

9x^2y^-2
= 9x^2(1/y^2)
= 9x^2 / y^2
= 9(-3)^2 / (2)^2
= 9(9) / 4
= 81 / 4
= 81 divided by 4
= 20 remainder 1
= 20 1/4

Answer: B

I think you've written the equation incorrectly. Maybe missed a sign. The way it sits the answer comes to 114.55.

9*-3*-3*√2

MY MISTAKE! Not √2 but 1/(2^2)

I believe the answer is A
