Question

Which of the following relationship represents the dual of the Boolean property x + x’y = x + y?

(a)  x’(x + y) = x’y’

(b)  x(x’y) = xy

(c)  x * x’ + y = xy

(d)  x’(xy’) = x’y’

(e)  x(x’ + y) = xy

Answer 1

The relationship x * x’ + y = xy represents the dual of the Boolean property x + x’y = x + y
