well, all you have to know is this: Then, you have to apply the chain rule to find the derivative of the inside function . So, here is your entire problem.
Sorry, I put down the wrong problem. The correction question is: f(x) = arctan(2^x)
Same principle. Let . Thus Do you know how to find the derivative of u?
So do you take the natural log of both sides now?

Yes, but to derive that rule you use natural logs.
