Question

Wyznacz zbiory:
1) A = {1,2,4,8}
B = {1,2,3,6}
A″ =
B″ =
A″ u B″ =
(A n B)″ =
A″ n B″ =
(A u B)″ =
2) A = {3,6,9}
B = {1,3,5,7,9}
A″ =
B″ =
A″ u B″ =
(A n B)″ =
A″ n B″ =
(A u B)″ =

Answer 1

1 )
A' = 3,6
B' = 4,8
A' U B' =  3,4,6,8
(A n B)' = 3,4,6,8
A' n B' = PUSTY
(A U B)' = PUSTY
2 ) 
A' = 1,5,7
B' = 6
A' U B' = 1,5,6,7
(A n B)' = 1,5,6,7
A' n B' = Pusty
(A u B)' = PUSTY
