It's nonsense. You can't plug in u1=e^x when u1 is an integration variable.

In terms of a differential, d(e^x) = e^x dx. From
there, it can be integrated in terms of x.

Since the integral is in terms of $u_1$ you just pull the $\frac{1}{e^x}$ outside the integral because you can just assume it's constant wrt $u_1$

I mean, unless they've told you otherwise

I think it's probably nothing. Just integrate as usual.

just do integration by parts. pull out the 1/e^x as the other anon said first. if you'd like you can use feynman's integration trick by differentiating the integral of x^a by a twice.
