Web1 mrt. 2024 · Solution: We need to determine the value of the product ab, given that a and b are positive integers. Statement One Alone: Knowing that the least common multiple (LCM) of a and b is 48 is not sufficient. For example, if a = 1 and b = 48, then ab = 48. However, if a = 2 and b = 48, then ab = 96. Statement Two Alone: WebProve if n2 is odd then n is odd. Proof (proof by contradiction): Assume n2 is odd and n is even. integer k n = 2k n2 = 4k2 = 2(2k2) Let m = 2k2. n2 = 2m So, n2 is even. Let p is “n2 is odd ”. p ¬p is a contradiction. By contradiction, if n2 is odd then n is odd.
