#### Question

What will be the values of input A and B for the Boolean expression `overline ((A +B) .(A*B)) =1?`

#### Solution

The truth table for the Boolean expression `overline ((A +B) .(A*B)) = is:`

A | B | (A+B) | (A,B) | (A+B).(A.B) | `overline ((A +B) .(A*B)) =1?` |

1 | 1 | 1 | 1 | 1 | 0 |

0 | 0 | 0 | 0 | 0 | 1 |

1 | 0 | 1 | 0 | 0 | 1 |

0 | 1 | 1 | 0 | 0 | 1 |

The output of this Boolean expression is 1 only when both the inputs A and B are 1.

The values of A should, therefore, be 1.
