Question

Dados os conjuntos A = { 0,1,2,3,4,5,7}, B = { 1,2,3} e C = { 3,5,6,8,9} , determine o que se pede.

a) AUBUC

b)A ∩B∩C

c) ( A- B) ∩C d) ( A - C) ∩ B

Answer 1

Resposta:

a) 0, 1, 2, 3 4, 5, 6, 7, 8, 9

b) 3

c) 5

d) 1, 2

Answer 2

Resposta:

a) AUBUC ={ 0,1,2,3,4,5,6,7,8,9}

b)A ∩B∩C ={ 5 }

c)( A- B) ∩C ={ 5 }

d) ( A - C) ∩ B =  { 1,2}

Explicação passo-a-passo:

A = { 0,1,2,3,4,5,7}, B = { 1,2,3} e C = { 3,5,6,8,9}

a) AUBUC  => AUB ={ 0,1,2,3,4,5,7} UC  = { 0,1,2,3,4,5,6,7,8,9}=>

AUBUC ={ 0,1,2,3,4,5,6,7,8,9}

b)A ∩B∩C => A ∩B=  { 1,2,3} ∩C => { 5 }

c) ( A- B) ∩C => ( A- B)= { 0,4,5,7} ∩C=  { 5 }

d) ( A - C) ∩ B => ( A - C) =  { 0,1,2,4,7} ∩ B = { 1,2}
