lim (2^h - 1)/ h

h->0

Thanks in advance.

If you use

lim dx->0 of [f(a + dx) - f(a)]/dx = f'(a)

and recognize 1=2<sup0.

Then use f(x)=2

Thus lim dx->0 [2

This means find d/dx 2

You can think of the dx as delta x, or increment of x.

I'm not sure if you've used L'Hospital's rule or not, but that's another way you could solve this problem too.
