Could I get some help
Not sure what to do when to the power of n.

Thanks
Just solve normally for constant term (when the two terms in the general term of the expansion will multiply to give you 0). The lower limit of nCr will be in terms of n rather than an integer value. So we don't find the constant term just an simplified expression for it.

You should get 2nCn

And as the above comments state, do it normally and you reach to the conclusion
