Webit’s not. Anything you can do with strong induction, you can also do with regular induction, by appropriately modifying the induction hypothesis. If P(n) is the statement you’re trying to prove by stronginduction,letP0(n)bethestatementP(1);:::;P(n) hold. Proving P0(n) by regular induction is the same as proving P(n) by strong induction. 12 Web3. Using strong induction, I will prove that integer larger than one has a prime factor.
