f'w = w X (1)(w^2+z^2)^2 X 2w + (w^2+z^2)^1 (1) = 2w^3 (w^2+z^2) + (w^2+z^2)^1

You have to check the last answer very carefully. You are doing this right, but you are making mistakes. Check them.

Which part is the mistake?

f'w = w X (1)(w^2+z^2)^2 X 2w + (w^2+z^2)^1  This is OK, but this = 2w^3 (w^2+z^2) + (w^2+z^2)^1 is not. Try to find the common denominator in the first one and subtract the fractions.
