Prove that {IFF} is not an adequate set of connectives

I've seen proofs by induction on how to prove a set of connectives isn't adequate, but I don't know how to apply it to IFF.

A subset of a power set. (a) Let X = {a, b, c, d}. What is { A: A ∈ P(X) and |A| = 2 }? comment: Please give a clear explanation to what this set builder notation translate to? Because I've checked the answer for a) and it is A= {{a,b}, {a,c}, {a,d}, {b,c}, {b,d}, {c,d}}. I don't understand because the cardinality of A has to be 2 right? Meanwhile, the answer is basically saying there's 6 elements. So...

Consider the following expression: 7^n-6*n-1 Using induction, prove the expression is divisible by 36. I understand the process of mathematical induction, however I do not understand how the solution showed the result for P_n+1 is divisible by 36? How can we be sure something is divisible by 36? Please explain in great detail.

Assume S is a recursivey defined set, defined by the following properties: 1 ∈ S n ∈ S ---> 2n ∈ S n ∈ S ---> 7n ∈ S Use structural induction to prove that all members of S are numbers of the form 2^a7^b, with a and b being non-negative integers. Your proof must be concise. Remember to avoid the following common mistakes on structural induction proofs: -trying to force structural Induction into linear Induction. the inductive step is...

Without using induction, prove that for x is an odd, positive integer, 3x ≡−1 (mod 4). I'm not sure how to approach the problem. I thought to assume that x=2a+1 and then show that 3^x +1 is divisible by 4 and thus congruent to 3x=-1(mod4) but I'm stuck.
