    You could use the product rule, have you tried that?

    Or the Quotient Rule...

    \displaystyle \begin{align*} \frac{d}{dx}\left(\frac{u}{v}\right) = \frac{v\,\frac{du}{dx} - u\,\frac{dv}{dx}}{v^2} \end{align*}

    I am confused by your use of parentheses.

    Do you mean z = (w^3/2)(w + c*e^(w))

    OR

    do you mean z = (w^3)/(2(w + c*e^(w))?
    See the difference?
