We use the Binomial Theorem in the special case where x = 1 and y = 1 to obtain 2n = (1 + 1)n = Xn k=0 n k 1n k 1k = Xn k=0 n k = n 0 + n 1 + n 2 + + n n : This completes the proof. Proof 2. Let n 2N+ be arbitrary. We give a combinatorial proof by arguing that both sides count the number of subsets of an n-element set. Suppose then ... Inductionyields another proof of the binomial theorem. When n= 0, both sides equal 1, since x0= 1and (00)=1.{\displaystyle {\tbinom {0}{0}}=1.} Now suppose that the equality holds for a given n; we will prove it for n+ 1.
