WebFirst we compute 82,642,834,671 mod(4) = 3. Then use this theorem: Theorem. If n is a positive integer such that n mod(4) is 2 or 3, then n is not a perfect square. Proof. We will prove the contrapositive version: "If n is a perfect square then n mod(4) must be 0 or 1." (Do you understand why this is the contrapositive version?) Suppose n = k 2 ... WebJan 19, 2024 · Yes, the contrapositive is "If x y ≠ 6 then x ≠ 2 or y ≠ 3 ". And it is true. To see that, consider the original statement itself (if the statement is true, so is the contrapositive). This is one of the cases where the truth of the contrapositive is less obvious than the truth of the original statement. Share Cite Follow

WebFeb 9, 2014 · The contrapositive would then read, "If n 2 is not even, then n is not even," or equivalently (since if a number is not even, it is odd): "If n 2 is odd, then n is odd." Let's prove this. If n 2 is odd, then n 2 = 2 m + 1 for some (nonnegative) integer m. Then 2 m = n 2 − 1 = ( n − 1) ( n + 1). But since the LHS is even, so must be the right. 4 rows ·
