    1. The problem statement, all variables and given/known data

    2. Relevant equations

    The derivative of e^anything = e^anything * (du/dx).

    3. The attempt at a solution

    So, wouldn't the answer choice be C? The derivative of e^nx = (e^nx)(n).

    No, it's not answer (C). (C) is the first derivative !

    Start by looking at [itex]\displaystyle \frac{d}{dx}e^{nx}\,,\ \ \frac{d^2}{dx^2}e^{nx}\,,\ \ \frac{d^3}{dx^3}e^{nx}\,, \ \ \text{etc.}[/itex]
