Multiply and, if possible simplify. Assume that all variables in radicand represent positive real numbers and no radicands involve negative quantities raised to even powers.
sqrt32xy * sqrt4xy^2

When I worked it out I got 4xy*sqrt8y, but apparently that's wrong and I'm not sure how to get to the correct answer.
