Question

Dados os conjuntos numéricos a seguir: A = {1, 2, 3, 7, 9}, B = {0, 2, 4, 6} e C = {1, 2, 4, 5, 7, 8} determine:

a) A ∪ B = *

b) B ∩ C = *

c) A ∪ B ∪ C = *

d) A ∩ B ∩ C = *

e) A – C = *




​

Answer 1

Resposta:

a) A ∪ B = {0,1,2,3,4,6,7,9}

b) B ∩ C = {2,4}

c) A ∪ B ∪ C = 

A ∪ B={0,1,2,3,4,6,7,9}

∪ C ={0,1,2,3,4,5,6,7,8,9}

d) A ∩ B ∩ C =  A ∩ B= {2} ∩ C= {2}

e) A – C = {3,9}
