$$\lim_{n\to \infty} \left[{\left({{n \choose 0}.{n \choose 1}.{n \choose 2}.\dots.{n \choose n}}\right)^\frac1{n^2+n}}\right]$$
I have tried to solve this question for a decent amount of time but with no avail,so I'd be grateful for any help provided.
ALSO:This may seem as a drag/nuisance, but are there any other alternate methods to solve this other than the one provided here?
