Question

considere os conjuntos pfv me ajudem e de matematica.​

Answer 1

Resposta:

A = {-5, -4, -3, -2}

B = {-1, 2, 3}

AxB = {(-5,-1), (-5,2), (-5,3), (-4,-1), (-4, 2), (-4,3), (-3,-1), (-3,2), (-3,3), (-2,-1), (-2,2), (-2,3)}

BxA = {(-1,-5), (-1,-4), (-1,-3), (-1,-2), (2,-5), (2,-4), (2,-3), (2,-2), (3,-5), (3,-4), (3,-3), (3,-2)}

Answer 2

Explicação passo-a-passo:

• A = {-5, -4, -3, -2}

• B = {-1, 2, 3}

a)

A x B = {(-5, -1), (-5, 2), (-5, 3), (-4, -1), (-4, 2), (-4, 3), (-3, -1), (-3, 2), (-3, 3), (-2, -1), (-2, 2), (-2, 3)}

b)

B x A = {(-1, -5), (-1, -4), (-1, -3), (-1, -2), (2, -5), (2, -4), (2, -3), (2, -2), (3, -5), (3, -4), (3, -3), (3, -2)}
