Question

Considere os conjuntos: A = {5, 10, 20, 25, 30, 35, 40}, B = {8, 10, 12, 18, 20, 22, 30, 35}, C = {10, 18, 20, 40, 45, 50, 60} Faça as seguintes operações: a) A ∪ B b) B ∪ C c) B ∪ A d) C ∪ A e) A ∪ A f) B ∪ ∅ g) A ∩ B h) A ∩ C i) B ∩ C j) C ∩ ∅ k) (A ∪ B) ∪

Answer 1

a) A ∪ B = {5, 8, 10, 12, 18, 20, 22, 25, 30, 35}

b) B ∪ C = {8, 10, 12, 18, 20, 22, 30, 35, 40, 45, 50, 60 }

c) B ∪ A = {5, 8, 10, 12, 18, 20, 22, 25, 30, 35}

d) C ∪ A = {5, 10, 18, 20, 25, 30, 35, 40, 45, 50, 60 }

e) A ∪ A = {5, 10, 20, 25, 30, 35, 40}

f) B ∪ ∅ = {8, 10, 12, 18, 20, 22, 30, 35}

g) A ∩ B = {10, 20, 30, 35 }

h) A ∩ C = {10, 20, 40}

i) B ∩ C = {10, 18, 20 }

j) C ∩ ∅ = ∅

k) (A ∪ B) ∪ = {5, 8, 10, 12, 18, 20, 22, 25, 30, 35}
