Question

Sendo A = {4, 5, 7, 8, 9, 10, 11, 12}, B = {1, 3, 4, 6, 9, 11, 12, 13} e C = {7, 9, 11, 12, 14}, Marque abaixo a resposta correta desta solução (C ∩ A) U (B ∩ C): 7 - 9 - 12 5 - 11 - 12 - 14 8 - 10 - 11 - 12 7 - 9 - 11 - 12 4 - 5 - 7 - 9 - 11

Answer 1

Resposta:

Explicação passo-a-passo:

A = {4, 5, 7, 8, 9, 10, 11, 12}

B = {1, 3, 4, 6, 9, 11, 12, 13}

C = {7, 9, 11, 12, 14}

(C ∩ A) U (B ∩ C)

({7, 9, 11, 12, 14} ∩ {4, 5, 7, 8, 9, 10, 11, 12}) U ({1, 3, 4, 6, 9, 11, 12, 13} ∩ {7, 9, 11, 12, 14})

{7, 9, 11, 12} U {9, 11, 12}

R = {7, 9, 11, 12}.
