Short answer: Raise the quantity in parentheses to the indicated exponent, and simplify the resulting expression. Express answers with positive exponents.
(-33xy^-1 / 66x^0y^-3)^2
This is my work:
=-33^2x^2(y^-1)^2 / 66^2(x^0=1=1^2)(y^-3)^2
=1089x^2y^(-1-2) / 4356*1y^(-3-2) =1089x^2y^-3 / 4356y^-5

I need the answer not to be a negative, how do I do that?

y^-3 / y^-5 = y^2

anonymous · Answer

answer then becomes
1089x^2y^2 / 4356

anonymous · Answer

is that ok?

Thank you this makes sense to me. Can you do the ys like that before you start the problem?
