: I have tried everything on this problem that I know to do. It involves a fraction and positive and negative exponents. Assume all variables represent positive real numbers. Write your answers with positive exponents.
(x^2 y^-3 z) ^1/2
_________________
x^1/2 y z^-1/2
first I multiiplied everything on the top by the exponent outside the ()
x^2/1*1/2, y^-3*1/2, z^1/2 = x y^-3/2 z^1/2
__________________________ _______________
x^1/2 y z^-1/2 x^1/2 y z^-1/2 This is where I get stuck
