So we have a definite answer to the Q.stem of a YES from statement 1. You can right away eliminate options B,C,E as statement 1 now is sufficient. Lets now attack statement 2. Webp = 2mn+m+n, then xy is odd. So if x and y are odd, then xy is odd. Therefore by contraposition, if xy is even, then either x or y is even. f) The contrapositive of this statement is: if either x or y is even, then xy is even. So assume that either x or y is even, say x is even. So ∃m ∈ Z such that x = 2m. Then xy = 2my = 2(my) which is even. fungible inventory

Web3.1.32 For all integers n and m, if n m is even then n3 m3 is even. Proof: Let n and m be integers such that n m is even. Therefore, n m = 2k for some k 2Z. Note that n3 m3 = (n m)(n2 +nm+m2) = 2k(n2 +nm+m2) = 2(k(n2 +nm+m2)): Let r = k(n2 +nm+m2). Since k(n2 +nm+m2) is an integer, n3 m3 = 2r, with r 2Z. Therefore n3 m3 is even. WebIf n^2 n2 is even, then n n is even. PROOF: We will prove this theorem by proving its contrapositive. The contrapositive of the theorem: Suppose n n is an integer. If n n is odd, then n^2 n2 is odd. Since n n is odd then we can express n n as n = 2 {\color {red}k} + 1 n = 2k + 1 for some integer \color {red}k k.
