Hi. I have a maths question on finding the turning points and determining their nature but I can't find the value of x and w.

The equation is z= e^(2x) + e^(-y) + e^(w^2) - e^(ln2x) - 2e^(w) + y

I differentiated it wrt to x, y and w.

But I can't solve for x and w in the following equations:

2e^(2x) - [ (e^ln2x) / x) = 0

2we^(w^2) - 2e^(w) = 0

I really need help for this one. Thanks.
