If `A = B = 1`, then in terms of Boolean algebra the value of `A.B + A` is not equal to.
A. B.A+B
B. B+A
C. B
D. None
A. B.A+B
B. B+A
C. B
D. None
Correct Answer – D
If `A =B=1`, then `A.B +A =1.1 +1=1`
then `overline(A).B= overline(1).1=0.1 =0`.
Correct Answer – D
AB + A = `1.1 + 1 = 1+1 =1`
Same is true for B. A+B as well as B+A.
