    Exponential problem derivative

    I can't seem to get the right answer for this problem (finding the derivative):

    \overline{c} = \frac{890}{q} + 3600 \cdot \frac{e^{(2q+4)/840}}{q}

    Help would be greatly appreciated.

    What is \overline{c}? If we assume that it's just functional notation, then:

    \overline{c}' = -\frac{890}{q^2}+3600\cdot \frac{e^{\frac{q+2}{420}} (q-420)}{420 q^2} using the chain rule on e^{\frac{2q+4}{840}.
