Is this the answear to 36x^2 y^4 a^-2
72a x^-1 y
^ means power
2 a^3 x^3 y^3 If this is not the answear then i don't know what to do.
No. You didn't change signs of the exponents when you move X^-1 from bottom to top. Same thing for the y.
Close, but now you have the x and y terms in the wrong place or they have the wrong signs. Try again.
