p: If x is an integer and x2 is even, then x is also even.Let q: x is an integer and x2 is even.r: x is even.To prove that p is true by contrapositive method, we assume that r is false, and prove that q is also false.Let x is not even.To prove that q is false, it has to be proved that x is not an integer or x2 is not even. x is not even implies that x2 is also not even.Therefore, statement q is false.Thus, the given statement p is true.
