Question

Пусть
U(1,2,3,4,5,6,7,8,9)
A (1,2,3,4,5,9)
B (2,4,6,8),
C (1,3,5,7)
D (1,2,4,5,7,8,9)
Выразить множество F через множества U A B C D ,если F (2,5,7,9)

Answer 1

1,2,3,4,5,6,7,8}

Пошаговое объяснение:

(-A V - B) = {6,7,8} V {1,3,5,7} = {1,3,5,6,7,8}

(-С Λ D) = {2,4,6,8} Λ {1,2,4,5,7,8} = {2,4,8}

(-A V - B) V (-С Λ D) = {1,3,5,6,7,8} V {2,4,8} = {1,2,3,4,5,6,7,8}
