2. ### For all integers a,b,c: if ab divides c, then a divides c and b divides c?

If ab | c, then there exists an integer n such that c = abn But also c = (bn)a = ka and c = (an)b = ma Therefore this directly implies a | c and b | c. You could also argue this through prime factorization and subsets.

5. ### Prove that if N is a normal subgroup of G then the multiplication on G/N given by aN*bN = abN is well defined?

Since N is normal bNb^-1 = N ==> aNbN = a(bNb^-1)(bN) = abN (b^-1b)N = abN1N = abN .
