Question

1) Dado o conjunto
A = {3, 4, 5, 6, 7, 8, 9, 10},
B = {9, 10, 11, 12}
C = {5, 7, 9,11, 13},
os elementos do conjunto (A∩B)UC são:
A) {5,7,9,11,13}
B) {5,7,9,10}
C) {3,4,5,7,11,13}
D) {5,7,9,10,11,13}
E) {3,4,5,6,7,8,9,10,11,12,13}

Answer 1

Resposta:

D) {5, 7, 9, 10, 11, 13}

Explicação passo-a-passo:

A∩B = {9, 10}

C = {5, 7, 9, 11, 13}

então

{9, 10} + {5, 7, 9, 11, 13} = {5, 7, 9, 10, 11, 13}

deu pra entender?
