Partial derivative?

Hello

I am currently stuck on two problems concerning partial differentiation:

1)Find the partial derivative of
∂m/∂q and ∂m/∂h for the function:

m=ln(qh - 2h^2)+2e^(q-h^2+3)^4 - 7

2) Find the partial derivative of ∂z/∂x for the function:

(z+1)^3y-(zx)^2-3=x/z-ln(xyz)-5xy^2

How do I solve this? And are they solved in the same way btw?

What are your thoughts? What have you done so far? Please show us your work even if you feel that it is wrong so we may try to help you. You might also read

As a hint, remember that all independent variables [assumed q and h in (1) and x and y in (2)], other than the one you are taking the partial derivative with respect to, are assumed to be constant when taking the partial derivative.

In a sense, yes they are both solved the same way except (1) can be done directly and (2) must be done implicitly.
