Question

Wypisz elementy podanych zbiorów.
a )A = {x ∈ N : x|6} =
B = {x ∈ N : x|14} =
C = {x ∈ N : x|15} =
b) Wyznacz poniższe zbiory.
A∩B∩C =
(AUB)∩C =
(A/B)∩C =
(A∩B)/C =
(AUB)/C =
(A/B)UC =
(A∩B)UC =
(A/B)/C =

Answer 1

A={1, 2, 3, 6}
B={1, 2, 7, 14}
C={1, 3, 5, 15}
A∧B∧C={1}
(A∨B)∧C={1, 3}
(A/B)∧C={3}
(A∧B)/C={2}
(A∨B)/C={2, 6, 7, 14}
(A/B)∨C={1, 3, 5, 6, 15}
(A∧B)∨C={1, 2, 3, 5, 15}
(A/B)/C={6}
