WebBinomial Theorem STATEMENT: x The Binomial Theorem is a quick way of expanding a binomial expression that has been raised to some power. For example, :uT Ft ; is a binomial, if we raise it to an arbitrarily large exponent of 10, we can see that :uT Ft ; 5 4 would be painful to multiply out by hand. Formula for the Binomial Theorem: := WebProof: (by induction on n) 1. Base case: The identity holds when n = 0: 2. Inductive step: Assume that the identity holds for n = k (inductive hypothesis) and prove that the identity holds for n = k + 1.! k+1 ... A combinatorial proof of the binomial theorem: Q: In the expansion of (x + y)(x + y)···(x + y),
