WebProof by Induction. Step 1: Prove the base case This is the part where you prove that \(P(k)\) is true if \(k\) is the starting value of your statement. The base case is usually showing that our statement is true when \(n=k\). Step 2: The inductive step This is where you assume that \(P(x)\) is true for some positive integer \(x\).

Web•Proof (by induction): Base Case: A(1)is true, since if max(a, b) = 1, then both a and b are at most 1. Only a = b = 1satisfies this condition. Inductive Case: Assume A(n)for n >= 1, and show that A(n+1). If max(a, b) = n+1, then max(a-1, b-1)= n. By the inductive hypothesis, a-1 = b-1, so a = b. •Corrollary: 3 = 5 •Proof: max(3, 5) = 5.
