Q. The Simplified form of a Boolean equation (AB’+AB’C+AC)(A’C’ +B’) is
(A) 0
(B) 1
(C) -1
(D) -2
Ans :- (A)
Explanation:-
(AB’+AB’C+AC)(A’C’ +B’)
On simplifying above equation,
(AB’A’C’+AB’CA’C’+ACA’C’+AB’B’+AB’CB’+ACB’)
(0+0+0+AB’+AB’C+ACB’)
Because multiplication of element with its complement is 0.
(AB’+AB’C)
AB’(1+C)
AB’
