Question

2) Dados os conjuntos: A = {0,1,2,4,5}, B = {0,2,4,6} e C = {1, 3, 5}
Determinar:

a) A−B
b) B−A
c) A−C
d) C−A
e) C−B
f) B−C
g) C−(A∪B)
h) C−(A∩B)
i) (A∩B)−A
j) (A∩C)−B
k) A−∅
l) ∅−A

Answer 1

a) A−B= {1,5}

b) B−A= {6}

c) A−C= {0,2,4}

d) C−A= {1,3}

e) C−B= {1,3,5}

f) B−C= {0,2,4,6}

g) C−(A∪B)= {1,3,5}- {0,1,2,4,5,6}= {3}

h) C−(A∩B)= {1,3,5} - {0,2,4}= {1,3,5}

i) (A∩B)−A= {0,2,4} - {0,1,2,4,5}= {}

j) (A∩C)−B= {1,5} - {0,2,4,6}= {1,5}

k) A−∅= {0,1,2,4,5}

l) ∅−A= {}

Acho que são assim!!
