Question

show that Lhs is equal to Rhs A+Ā.B=A+B this is +1 computer science question ​

Answer 1

To prove

A + A.B = A+B

Let A = 1 and B = 2

Considering LHS, i.e.

A + A.B = 1 + 1.2

            = 1 + 2

            = 3

Considering RHS,

A + B = 1 + 2 = 3

Hence, LHS = 3        RHS = 3

Therefore, LHS = RHS
