Webb17 aug. 2024 · The Induction Step. In this part of the proof, we’ll prove that if the power rule holds for n = m - 1, then the case for m is also true. I’ve chosen to use m instead of n for this part since I’ve already used n for the power of x.If the power rule didn’t hold for n = m - 1, then it wouldn’t matter if the case for n = m is true, so we will assume that the power … WebbAnd then we're going to do the induction step, which is essentially saying "If we assume it works for some positive integer K", then we can prove it's going to work for the next positive integer, for example K + 1. And the reason why this works is - Let's say that we prove both of these. So the base case we're going to prove it for 1.

WebbProof: By strong induction. Let P(n) be “n is the sum of distinct powers of two.” We prove that P(n) is true for all n ∈ ℕ. As our base case, we prove P(0), that 0 is the sum of distinct powers of 2. Since the empty sum of no powers of 2 is equal to 0, P(0) holds.
