Questão 03 Dados A = {–2, –1, 0} e B = {1, 2, 3}, então determine: a) A x B c) B2 b) B x A d) A2

a) A x B = {(-2, 1), (-2, 2), (-2, 3), (-1, 1), (-1, 2), (-1, 3), (0, 1), (0, 2), (0, 3)} b) B x A = {(1, -2), (1, -1), (1, 0), (2, -2), (2, -1), (2, 0), (3, -2), (3, -1), (3, 0)} c) B² = {1, 4, 9} d) A² = {4, 1, 0}
