For the sets a = {a, b} and b = {a, b,c}, determine ax b, bx a, a2 = ax a and b2 = bxb.

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.

i dont know sorry
