WebJan 19, 2024 · 3 Answers. 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. 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.

WebSep 29, 2024 · Contrapositive: if not q, then not p not q: "It (the polygon) is a triangle." not p: "A polygon does not have more than 3 sides." which also means "A polygon has 3 sides or less." Given that the shape in the question is a polygon, the fewest number of sides any polygon can have is 3. This puts an additional constraint on "not p". WebFeb 5, 2015 · The contrapositive of this statement should be, (If x is rational, then x is rational) Then I end up with x = m 2 n 2 for m, n to be integers and n does not equal 0. Is it careless to be done with the proof since we are saying that x = m 2 n 2 is a rational number therefore the contrapositive is true, therefore the original statement is also true? how to uninstall origin games
