Simplification Help: Can't Simplify Further?

[7yler]

I have worked a question down to this, but I am not sure how to simplify any further.

I think that has been simplified enough. I see no way to simplify it any further...

= 3 - \frac{3x+y}{x\left(2yx^5 e^{-2y} -1\right)} ??

But that's not really simplification

The original question was: suppose x^{6}e^{-2y}=ln(xy)

Find \frac{dy}{dx} by implicit differentiation.

That is the answer that I have come to, but it is said to be wrong.

And can you posts what you did to get to that solution?

Well, you should calculate once more the partial derivative wrt y.
