First question, what are equivalent sets? My prof said that sets are equivalent if they have the same cardinality, but a few other sources I have read say that equivalency means having the exact same elements in both sets.
Second, can two non-equivalent sets (going my my prof's definition) have a Cartesian product?
The problem (simplified to the final steps) is A x B, where A = {a,e,g.n} and B = {s,q,u,a,r,e}. Obviously n(A)=4 and n(B)=6, so I'm guessing that there is no Cartesian product and the answer is null?
