Use a truth table to prove the identity (A+B)(A¯B+AB)=B
Use a truth table to prove the identity (A + B)(A + AB) = B. Drag the appropriate labels to their respective targets. Note: all targets should be filled in.Solution
As shown above, the column B and last column are equal
Hence proved
| A | B | A+B | A\' | AB | A\'+AB | (A+B)(A\'+AB) | |
| 0 | 0 | 0 | 1 | 0 | 1 | 0 | |
| 0 | 1 | 1 | 1 | 0 | 1 | 1 | |
| 1 | 0 | 1 | 0 | 0 | 0 | 0 | |
| 1 | 1 | 1 | 0 | 1 | 1 | 1 |
