Distributive law:
A.(B+C) = A.B+ A.C
For verification of the above distributive law
B___C____A____B+C_____A.(B+C)
0___0____0_____0_______0
0___0____1_____0_______0
0___1_____0_____1_______0
0___1_____1_____1_______1
1___0_____0_____1_______0
1___0_____1_____1_______1
1___1_____0_____1_______0
1___1_____1_____1_______1
B__C___A___A.B___A.C__A.B+A.C
0___0____0_____0_______0____0
0___0____1_____0_______0_____0
0___1_____0____0_______0____0
0___1_____1_____0______1_____1
1___0_____0____0_______0____0
1___0_____1_____1_______0_____1
1___1_____0_____0______0_____0
1___1_____1_____1_______1_____1
By looking last entry of both the tables we can see that
A.(B+C) = A.B+ A.C
Hence proved
A.(B+C) = A.B+ A.C
For verification of the above distributive law
B___C____A____B+C_____A.(B+C)
0___0____0_____0_______0
0___0____1_____0_______0
0___1_____0_____1_______0
0___1_____1_____1_______1
1___0_____0_____1_______0
1___0_____1_____1_______1
1___1_____0_____1_______0
1___1_____1_____1_______1
B__C___A___A.B___A.C__A.B+A.C
0___0____0_____0_______0____0
0___0____1_____0_______0_____0
0___1_____0____0_______0____0
0___1_____1_____0______1_____1
1___0_____0____0_______0____0
1___0_____1_____1_______0_____1
1___1_____0_____0______0_____0
1___1_____1_____1_______1_____1
By looking last entry of both the tables we can see that
A.(B+C) = A.B+ A.C
Hence proved
