Question

SUPPOSE TWO SETS A ={a,b} and B={1,2,3,x,y} find A.B

Answer 1

Answer:

if A and B are two non-empty sets, then their Cartesian product A × B is the set of all ordered pair of elements from A and B.

        A × B = {(x, y) : x ∈ A, y ∈ B}

Suppose, if A and B are two non-empty sets, then the Cartesian product of two sets, A and set B is the set of all ordered pairs (a, b) such that a ∈A and b∈B which is denoted as A × B.
