Информатика,8 класс,срочно надо решить логические уравнения 1.(Not X▲Not Y)▼Not X 2.Not A▲(Not A▲B)▲A▼B▼Not A 3.A▲B▲(C▼Not A▼A▲C)▲Not B 4.Not(X▼Y)▼Not(X▲Z)▼Not(X▲Y▲Z)
2) Not A ⋀ (Not A ⋀ B) ⋀ A ⋁ B ⋁ Not A = Not A ⋀ B ⋀ A ⋁ B ⋁ Not A = 0 ⋀ B ⋁ B ⋁ Not A =
0 ⋁ B ⋁ Not A = B ⋁ Not A
3) A ⋀ B ⋀ (C ⋁ Not A ⋁ A ⋀ C) ⋀ Not B = A ⋀ B ⋀ (C ⋁ Not A) ⋀ Not B = A ⋀ С ⋀ B ⋀ Not B =
A ⋀ С ⋀ 0 = 0
4) Not(X ⋁ Y) ⋁ Not(X ⋀ Z) ⋁ Not(X ⋀ Y ⋀ Z) = (Not X ⋀ Not Y) ⋁ (Not X ⋁ Not Y) ⋁ Not Х ⋁ Not Y ⋁ Not Z = (Not X ⋀ Not Y) ⋁ Not Х ⋁ Not Y ⋁ Not Z = Not Х ⋁ Not Y ⋁ Not Z

1) .(Not X ⋀ Not Y) ⋎ Not X = Not Х
2) Not A ⋀ (Not A ⋀ B) ⋀ A ⋁ B ⋁ Not A = Not A ⋀ B ⋀ A ⋁ B ⋁ Not A = 0 ⋀ B ⋁ B ⋁ Not A =
0 ⋁ B ⋁ Not A = B ⋁ Not A
3) A ⋀ B ⋀ (C ⋁ Not A ⋁ A ⋀ C) ⋀ Not B = A ⋀ B ⋀ (C ⋁ Not A) ⋀ Not B = A ⋀ С ⋀ B ⋀ Not B =
A ⋀ С ⋀ 0 = 0
4) Not(X ⋁ Y) ⋁ Not(X ⋀ Z) ⋁ Not(X ⋀ Y ⋀ Z) = (Not X ⋀ Not Y) ⋁ (Not X ⋁ Not Y) ⋁ Not Х ⋁ Not Y ⋁ Not Z = (Not X ⋀ Not Y) ⋁ Not Х ⋁ Not Y ⋁ Not Z = Not Х ⋁ Not Y ⋁ Not Z
