(ii)Prove the statement ,"Product of two odd integers is odd,"by proving its contrapositive.

If the product of two consecutive odd numbers is 399, find the numbers.

a)Write the sets of all possible integers whose cube is odd.

Write the contrapositive of the statement: “If the integer n is odd, then n^2 is odd."

Find the sum of odd integers from 1 to 2001

Prove that the product of two consecutive even numbers added to 1 gives a perfect square.

Consider the statement,"If x is an integer and x^2 is even, then x is also even." prove the statement by the contrapositive method.

In each of the following , determine whether the statement is true or false. If it is true, prove it. If it is false, give an example. If x in A and A in B then x in B

(a)Check whether the following statement is true or not:"If x and y are odd integers,then xy is an odd integer".

State the converse and contrapositive of each of the following statements : p : A positive integer is prime only if it has no divisiors other than 1 and itself

One added to the product of two altenatlve integers gives '169 .' What are the numbers?
