Sejam A = { 1, 2, 3} e B { 7, 8, 9} o produto cartesiano A X B será igual a :

A x B = { (1,7) , (2,8), (3, 9) }

A x B = { (7,1), (7,2), (7,3), (8,1), (8,2), (8,3), (9,1), (9,2), (9,3)}

A x B = { (7, 1), (8, 2), (9, 3) }

A x B = { 1,1), (2,2), (3,3), (7,7), (8,8), (9,9)}

A x B = { (1,7) , (1,8), (1, 9), (2,7) , (2,8), (2, 9), (3,7) , (3,8), (3, 9) }
