1. The problem statement, all variables and given/known data Using only the axioms for a field, give a formal proof for the following: a) 1/z1z2 = 1/z1 1/z2 b) 1/z1 + 1/z2 = z1 + z2/z1z2 3. The attempt at a solution I really am having a tough time understanding this problem. I know the axioms of a field i.e. associativity and commutativity for addition and multiplications (those are the only axioms she cares about) but how do i use these to show the above is true?
