Question

Problem 4 [25 points]: Contradiction
Given a proof by contradiction of the statement:
If n? + 11 is odd then n is even

Please use the following definitions of even and odd numbers:
• An integer a is even if there exists an integer z with a = 2z.
• An integer a is odd if there exists an integer z with a = 2z + 1.
Your proofs may use the fact that every integer is either even or odd, but not both.

If you take any 3 digit number (ex. 123) and rewrite it as a 6 digit number by repeating the same 3 digit number (123123), you can divide by 13 then 11 then 7 and get the original 3 digit number. Write a proof for this this (might need to be a proof by contradiction)

Problem 2.4 (Grade a "Proof"). Study the following claim as well as the "proof": Claim. For any given integer m, m² is even only if m is even. "Proof". Assume that m is even. This means m = 2k for some integer k. Therefore, we have m² = (2k)? = 4k² = 2(2k²), with 2k² being an integer. Consequently, m² is even. In conclusion, m² is even only if m is even. Complete the following questions concerning the above claim and "proof": (1) Determine whether the "proof" is rigorous. Identify the issues in the "proof", if any. (2) Determine whether the claim is true or false. Justify the answer in part (3). (3) If the the claim is true and the "proof" is not rigorous, then provide a correct and rigorous proof. If the claim is false, give a concrete counterexample.
