WebProof: By strong induction. Let P(n) be “n can be written as the sum of distinct powers of two.” We prove that P(n) is true for all n. As our base case, we prove P(0), that 0 can be written as the sum of distinct powers of two. Since the empty sum of no powers of two is equal to 0, P(0) holds.

WebStrong induction is a type of proof closely related to simple induction. As in simple induction, we have a statement P(n) P ( n) about the whole number n n, and we want to prove that P(n) P ( n) is true for every value of n n. To prove this using strong induction, we do the following: The base case.
