Prove "If p: S→ s' is an isomorphism of (S,*) and (S',* '), then if * is commutative then ' is commutative." That is, prove that the commutative property of a binary structure (S, *) is a structural property. You are required to justify each statement. Here are the first three steps of the proof. I have started step 4 for you. These steps will be given on the test. Make sure you state the conclusion of the proof in the last step of the proof. 1) Given p: S → S'is an isomorphism of (S,+) and (S', '). 2) Suppose * is commutative. 3) Let a, beS and a', b'e S' 3 p(a) = a' and o(b) = b' 4) Now consider, 9. Given the subset (iR,+) of the group of (C,+) a) Prove the subset is closed under addition. b) Show that zero is the identity element of the set. That is, show 0 is in the set. c) Prove that the set does contain all of the inverses of its elements.
