If that's and then the difference is quite marked.

As you've written it, perhaps nothing. You need some care with you exponents.

If you meant

e^(2x) and e^(x^2)

then the latter is much bigger in general.

For example if x is 3 then

e^(2x) = e^6
e^(x^2) = e^9

Do note also that (e^x)^2 = e^(2x) so

(e^x)^2 is not the same as e^(x^2)

in general.
