Постройте таблицу истинности для следующих логических выражений. 1. F(x1, x2, x3) = x3\/(x2&x1&x3)​

1. a = 10; b = 5;
not (a < 5) -> not (5 < 5) -> not false -> true -> a = 5
ответ: 5

2. a = 10; b = 5; 
(a > 5) and (a < b) -> (10 > 5) and (10 < 5) -> true and false -> false
ответ: 10

3. a = 10; b = 5; 
(a > 1) or (a < b) -> (10 > 1) or (10 < 5) -> true or false -> true -> a = a-5 = 10-5 = 5
(a > 1) and (a = b) -> (5 > 1) and (5 = 5) -> true and true -> true -> a = a-5 = 5-5 = 0
ответ: 0

4. a = 10; b = 5; 
(a > 1) and (a < b) -> (10 > 1) and (10 < 5) -> true and false -> false
(a > 1) and (a = b) -> (10 > 1) and (10 = 5) -> true and false -> false
ответ: 10

5. a := 10; b := 5; 
(a > 1) and (a < b) -> (10 > 1) and (10 < 5) -> true and false -> false -> a = a + 7 = 10+7 = 17 
ответ: and

6. a = 10; b := 5; 
(a < 1) or (a > b) -> (10 < 1) or (10 > 5) -> a = a-7 = 10-7 = 3
ответ: or

7. a = 10; b = 5; 
(a < 1) and (a > b) -> (10 < 1) and (10 > 5) -> false and true -> false -> a = a + 5 = 10+5 = 15 
ответ: and
