the other one came out wrong. 8x^2y^-2 (4xy^2)^-1 ________ . ___________ x^-2y x^2y its a fraction and you have to multiply I assume you mean [(8x^2 y^-2)/(x^-2 y)] x [(4xy^2)^-1/(x^2 y)] which can be rewritten = 8 x^4 y^-3 x [1/(4x^3y^3)] = 2 x y^-6

need help again!!!!! Simplify the expression. Use only positive exponents. 8x^2 y^-2 . (4xy^2)^-1 __________ ____________ x^-2y x^2y i'm sorry i can't read your question that well. use "/" sign for fractions and "*" sign for multiplication please.
