    Some rules for you to use...

    \int e^x dx = e^x + C where C is a constant.

    \int a f(x) dx = a \int f(x) dx where a is a constant and f(x) is some function.

    Constant rule?

    Is this the way to start:
    \int 3e^x dx= 3e^x + C

    Although it is the correct answer, you should start by taking the constant 3 out of the integral sign.
