Suppose (x^2)*(e^(2y))= ln(xy)
Find dy/dx by implicit differentiation.

2x(e^(2y) ) + x^2(e^(2y) )(2dy/dx)= 1/(xy) (xdy/dx + y)
2x e^(2y) 2y x^2 e^(2y) = (1/y) dy/dx + 1/x
2x e^(2y)  1/x = dy/dx (1/y + 2x^2 e(2y) )
dy/dx = ( 2x e^(2y)  1/x ) / ((1/y + 2x^2 e(2y)) )
still pretty messy looking, I don't know how far you have to take it.
Also, you better check my work. It is always harder to just type it here, rather than do it on paper.
