Question

Solve h,i and j please .

Answer 1

Ans H)

A = 1, B= 0, C= 1

X = A*B + bar(B+C)

bar(B+C) = bar(B)*bar(C) = bar(0)*bar(1)

= 1*0 = 0

now X = A*B + 0 = 1*0 + 0 = 0 + 0 = 0

I) See image attached

J) (A'+B')(A+B) = A'(A+B) + B'(A+B)

= A * A' + A' * B + B' * A + B' * B      (A * A' = 0, B * B' = 0)

= 0 + A' * B + B' * A + 0

= A' * B + A * B'

Hence Proved
