Question

rewrite with positive exponents. assume that even roots are nonnegative quantities and that all are denominators are zero (4xy^-2)^-2

Answer 1

im confused is the answer (4xy^-2)^-2 = 4xy^4 OR y^4/16*x^2

Answer 2

\[\large \begin{array} )(4xy^{-2})^{-2} \implies \frac{1}{(4xy^{-2})^2}\implies \frac{1}{16x^2y^{-4}} \implies \frac{y^4}{16x^2}\end{array}\]
does that help?

Answer 3

yes it does thank you!

Answer 4

welcome ^_^
