"Find the instantaneous rate of change of w with respect to z if w=(7/3z^2)"
excuse the primitive equation...any help???

Just differentiate it with respect to z.

HallsofIvy

Is that w= (7/3)z² or w= 7/(3z²)?

I suspect the former which should be easy to differentiate using
(zⁿ)'= n z^n-1. If the latter, write it as w= (7/3)z^-2 and use the same rule.
