%28n%2B1%29%5Ek-n%5Ek Start with the given expression


Expand %28n%2B1%29%5Ek using the Binomial Theorem

Group like terms

Notice the n%5Ek terms cancel out since n%5Ek-n%5Ek=0. So we're left with



Now the term with the highest exponent value is kn%5E%28k-1%29. So this means that the degree of %28n%2B1%29%5Ek-n%5Ek is k-1
