Is e² treated as a constant?

Yes. Or you can use the chain rule. if u = f(x) = 2 and y = g(u) = e^u then

\frac {dy} {dx} = \frac {dy} {du} \frac {du} {dx}

since \frac {du} {dx} = 0 \frac {dy} {dx} = 0.

Not only is it treated as a constant, it is a constant. The derivative of any constant is zero. Period.

Using the chain rule certainly works, but it's definitely overkill, so not recommended.
