Question

Dados los siguientes conjuntos: A={1,2,3,4,5,6,7}, B={1,5,8,10} y C={1,2,9,11,12}, realizar las
siguientes operaciones:
a) A U B=
b) A U B U C=
c) A Ո B=
d) A Ո C=
e) B Ո C=
f) A Ո B Ո C=
g) A U ( B Ո C)=
h) A – B=
i) A – (B Ո C)=
j) (A – B) U (A – C)=

Answer 1

Respuesta:

A U B=  [ 1,2,3,4,5,6,7,8,10]

A U B U C= [1,2,3,4,5,6,7,8,9,10,11,12]

A Ո B= [ 1,5]

A Ո C=  [1,2]

B Ո C= [1]

Explicación:

A Ո B Ո C= [1]

g) A U ( B Ո C)= [1,2,3,4,5,6,7]

h) A – B= [2,3,4,6,7]

i) A – (B Ո C)= 1

j) (A – B) U (A – C)= [2,3,4,5,6,7,9,11,12]

A-C= [3,4,5,6,7,9,11,12]

ENTONCES:
