Simplify the exponential expression. Assume the variables represent nonzero real numbers.
(2^-1 x^-5 y^-5)^-2 (2x^-2 y^4)^-2(4x^-2 y^4)^0
______________________________________
(2x^-5 y^-5)^2
the line by the way means to divide. i have no idea how to solve :( All i know is the (4x^-2 y^4)^0 is equal to 1 and that kinda cancels itself out.
