Zero to the power of zero - Wikipedia
That is, r 0 = 1 for each real number r, including 0. The same argument applies with R replaced by any ring. Defining 0 0 = 1 is necessary for many polynomial identities. For example, the binomial theorem (1 + x) n = Σ n k=0 (n k) x k holds for x = 0 only if 0 0 = 1. Similarly, rings of power series require x 0 to be defined as 1 for all ...
