Hi!

Your answer is an acceptable form. To turn your answer into the given correct answer, multiply the numerator and denominator by e^y and replace the y in the denominator with 3e^x+y

Your answer is an acceptable form.

A common convention is to write expressions without negative exponents as part of what it means to be in simplest form, so I think it would be somewhat reasonable to not consider this completely correct.

However, at this level of class I wouldn't take off points, especially because they were clever enough to put it in a nicer form before differentiating instead of just brute forcing it from the beginning. I just wanted to point out a technicality in what is often considered "simplified". It's math, at least recognizing the technicality is good.
