The limit is "e"...To convince yourself,use the fact that the limit & the natural logarithm commute.
Daniel.
can you take me one step further than that, to get the answer e?
i got it now, thanks for the help

There would be another way to do it,directly,without use of ln .Just factor e^{x} and then use the definition of "e":
\lim_{u\rightarrow +\infty}(1+\frac{1}{u})^{u}=e
