Please answer this Discrete Mathematics question. Please show all steps, show the contrapositive for (a) and (b), and then prove the contrapositive for (a) and (b).

2 Contrapositives Write down the contrapositive of each of the following propositions. Then prove the contrapositive. a) If the product of two positive numbers is greater than 100 than at least one of the numbers is greater than 10. b) If a number is negative then it is not a perfect square. (11. is a perfect square if there is some m E Z such that n = m - m.)
