simplify the expression. Use only positive exponents.
8x^2y^-2/x^-2y * (4xy^2)^-1/x^2y
Something does not seem right in your terms.
Are you saying that 8x is being taken to the 2y power and that all this being taken to the -2x power?
Please clarify your terms, and we will do our best to help you — but not do the work for you.
I hope this helps. Thanks for asking.
