1. (40 marks) Prove the following statements. Explicitly state the type of proof you are using and clearly describe each step of the proof. (a) (5 marks) If x and y are both odd integers, then x+y is an even integer. (b) (5 marks) If x and y are positive, even integers, then x x y is divisible by 4 (c) (10 marks) (x mod 2)x (y mod 2) = (x x y) mod 2, where the mod operator gives you the remainder of the division (e.g. 3 mod 2 -1) (d) (5 marks) For any integers, x and y, X ye7 implies that x 2 4 or y 2 4 (e) (5 marks) For every integer n, n2 n is even. ( (10 marks) If x is a rational number and y is an irrational number, then the sum of x and y is irrationalStep by Step Solution
