calculus - Computing limxtoinftyxbiggl[frac1eleft(fracxx+1right)xbiggr]

I'm having some trouble solving finding the limit of:



limxx[1e(xx+1)x]



I can see that (xx+1)x=(1+1x+1)x1e. That's why I thought the limit is 0. However, according to WolframAlpha it's 12e.


I tried to write 1e(xx+1)x as a series but I didn't find a way to...


What's the right approach to find this limit?
