WebAnswer (1 of 4): Neither even nor odd roots are special, in fact—the only special case is the number zero, as far as roots are concerned, because it only has one n-th root for any n. For any nonzero [real or complex] number, that number has exactly (n) complex n-th roots, and they form the verti...
