Question

I got a different answer,
I answered the following question in a practice test and got it wrong. My answer was x^{2}y ^{3}, the answer key says the answer is y ^{2}x^{3} can anyone help?

question-=>
sqrt{xy}/sqrt{x ^{-5} y ^{-3}}

Answer 1

You can combine the square roots to get


sqrt( (xy)/(x^(-5)y^(-3) ) )


did you have that step?

Answer 2

When you combine the square roots you get
\[\sqrt{\frac{xy}{x ^{-5}y ^{-3}}}\]
Can you carry on to the next step?
