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.
