Answer: Hello!
the cross product between sets is defined as:
if A = {a,b,c} and B = {1,2,3)
then
where the A took the place of the columns, and B for the files.
then if our sets are A = {a,b} and B = {a,b,c)
a) AxB
b) BxA
c) AxA
d) BxB
Hope it helps, i know that is kinda hard work with this kind of operations, i tried to make a kinda of map in the first part so you can replace the values of A and B and do the multiplications by yourself, if you have troubles don't doubt of asking.
