(i) Write the contrapositive, converse, and inverse. Indicate as best as you can which of these statements are true and which are false. Give a counterexample for each that is false. (a) For all integers d, d is a prime integer only if d is not a perfect square. (b) For all real numbers a and b, if a < b then a² < b². (c) For all integers n, n 2 is divisible by 4 unless n is not divisible by 4.
