Hi.

In a question, the correct answer is

\( \frac{-3}{ \sqrt[4]{x^7}}~dx \)

the code answer is: dy = (a/b) / x^(c/d) dx;

but the student wrote a correct answer and the system says "incorrect"

I thougth that the system uses "dx" like: dy = (a/b) / **( **x^(c/d) dx **)**; but no. I changued de answer " -3 / ( x^(7/4) dx ) " and the answer is is bad too.

Can you help me?
