Let us consider the expression M^M+1, where M is a positive integer.

It can be verified that M=3 is the least value for which 2² divides M^M+1.

Given that n is a positive integer, find the least value of M (in terms of n) for which M^M+1 is divisible by 2ⁿ.

I forgot to add 1 to m^m. Ignore my previous posts.
