2x^-2 y^-2 if x = 3 y = -2

(assuming you are looking for the answer letting x=3 and y=-2)

2x^-2=2/9

y^-2=-1/4

Step-by-step explanation:

It seems like you have 2 different equations there. Them being 2x^-2 and y^-2 because the two equations aren't connected.

If this is the case you simply substitute and solve!

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
