x1→(x2∧x3∨x4∧x5∨x6∧x7) при
x1 x2 x3 x4 x5 x6 x7 F
0 1 0 1 1 1 0 0
0→(1∧0∨1∧1∨1∧0) = 0→1 = 1, а F=0. Не подходит

2.
x2→(x1∧x3∨x4∧x5∨x6∧x7) при 
x1 x2 x3 x4 x5 x6 x7 F
0 1 0 1 1 1 0 0
1→(0∧0∨1∧1∨1∧0) = 1→1 = 1, а F=0. Не подходит

3.
x3→(x1∧x2∨x4∧x5∨x6∧x7) при
x1 x2 x3 x4 x5 x6 x7 F
0 1 0 1 1 1 0 0
1→(0∧1∨1∧1∨1∧0) = 1→1 = 1, а F=0. Не подходит

4.
x4→(x1∧x2∨x3∧x5∨x6∧x7) при
x1 x2 x3 x4 x5 x6 x7 F
0 1 0 1 1 1 0 0
1→(0∧1∨0∧1∨1∧0) = 1→0 = 0 - верно

x1 x2 x3 x4 x5 x6 x7 F
1 0 1 1 0 0 1 0
1→(1∧0∨1∧0∨0∧1)=1→0 = 0 - верно

x1 x2 x3 x4 x5 x6 x7 F
0 1 0 1 1 0 1 0

1→(0∧1∨0∧1∨0∧1)=1→0 = 0 - верно

ответ: Выражение x4→(x1∧x2∨x3∧x5∨x6∧x7) соответствует F.
