Strong induction product of primes

Web1. Let P(n) be “n is a product of primes”. We will show that P(n) is true for all integers n ≥ 2by strong induction. 2. Base Case (n=2): 2 is prime, so it is a product of primes. Therefore P(2) is true. 3. Inductive : Suppose that for some arbitrary integer k ≥ 2, P(j) is true for every integer jbetween 2 and k 4. Inductive Step: WebBase: 2 can be written as the product of a single prime number, 2. Induction: Suppose that every integer between 2 and k can be written as the product of one or more primes. We need to show that k +1 can be written as a product of primes. There are two cases: Case 1: k + 1 is prime. Then it is the product of one prime, i.e. itself. Case 2: k ...
