Question

adi
5 - Dados os conjuntos A = {2, 4, 8, 12, 14}, B = {5, 10, 15, 20, 25} e C = {1, 2, 3, 18, 20},
determine:
a) A-C
b) B-C
c) (C-A) n (B-C)
d) (A-B) U (C-B)​

Answer 1

Resposta:

a) A-C={4, 8, 12, 13}

b) B-C={5, 10, 15, 25}

c) (C-A)∩(B-C)

(1, 3, 18, 20)∩(5, 10, 15, 25)

Ø

d) (A-B)U(C-B)

(2, 4, 8, 12, 14)U(1, 2, 3, 18)

(1, 2, 3, 4, 12, 14, 18)
