Question

1 – Dados os conjuntos A = {0, 1, 2, 3, 4, 5, 6, 7}, B = {2, 3, 4, 5} e C = {−2, −1, 0, 1, 2, 3}.
Determine:
a) A U B =
b) A ∩ B =
c) B U C =

d) A ∩ B ∩ C =
e) (A ∩ B) U C =
f) A – B =

g) (B – C) ∩ (A – C) =
h) (A U B) – C =
i) A U B U C =

Answer 1

resposta:

a) AUB = {0,1,2,3,4,5,6,7}

b) A∩B = {2,3,4,5}

c) BUC = {-2,-1,0,1,2,3,4,5}

d) A∩B∩C= {2,3}

e) (A∩B)UC = {-2,-1,0,,2,3,4,5}

f) A-B = {0,1,6,7}

g) (B-C)∩(A-C)= {4}

h) (AUB)-C ={4,5,6,7}

i) AUBUC= {-2,-1,0,1,2,3,4,5,6,7}
