Best ResponseYou've already chosen the best response.0It's a simple \(u=e^x3,\, du=e^xdx\) substitution.\[ \int \frac{e^{2x}}{e^x3}dx = \int\frac{u+3}{u}du = \int 1 + \frac{3}{u}du \]

Best ResponseYou've already chosen the best response.1Note: It's not "times" dx. There is no multiplication, there.

Best ResponseYou've already chosen the best response.0Oh that's true. So which one of the answers is the correct way to solve then? Integration is a real struggle for me

Best ResponseYou've already chosen the best response.1Well, you are supposed to be learning. A bit of difficulty should not be construed as a bad sign. Put in the time and thought. Looks like wio and DHASHNI already did most of the work for you. You do the rest.
