Ответ учителя по предмету Информатика
Ответ:
Логическое умножение на 0 дает 0.
(1 & 0) & ( 0 + A) & (1 & 0) = 0&( 0 + A)&0 = 0
Обегчим выражение, раскрыв скобки
F = (не А + не В) & (не В & A) = не А& не В & A + не В & не В & A =
= 0 + не В & не В & A = Этим образом, функция будет равна 1 только в одном случае: когда B=0 и A=1
A B F
0 0 0
0 1 0
1 0 1
1 1 0
