ANSWER
E x A = {(a, a), (a, e), (a, i), (f, a), (f, e), (f, i)}
Explanation:
Given information
Set A = { a, e, i}
Set E = {a, f}
Find E x A?
E x A means the cross product of set E and A
In mathematics, the cross-product of sets E and A are in ordered pairs of x and y. This implies that all the elements in set E are x and all the elements in set A are y
E x A = {(a, a), (a, e), (a, i), (f, a), (f, e), (f, i)}
