Let A be the set of all divisors of 11 and let B be the set of all divisors of 6. Construct the power set of A - B. Is this the same as the set-difference of the power set A minus the power set of B? Justify your answer.

Let A = : {3, 4, 5, 6, 9}, Write down each of the following sets. (a) An B. (b) {b-2: be B and b+ 2 & A}. B = = {2, 3, 7, 8, 9, 10}. Now write down each of the following numbers. (c) The number of 3-element subsets of B. (d) The number of non-empty subsets of B. Describe all of the following sets by listing their elements. (e) The set of composite numbers less than 17. (f) (a ≤N Icm(a, 6) = 42}. (g) The set of complex numbers z such that z4 = 1. [No justification is required for any parts of this question.]
