Question

Prove the following properties of Boolean algebras: Give a reason for each step. a. (x + y) + (y · x') = x + y b. (y + x) · (z + y) + x · z · (z + z') = y + x · z c. (y' · x) + x + (y + x) · y' = x + (y' · x)

          Prove the following properties of Boolean algebras: Give a reason for each step.
a. (x + y) + (y · x') = x + y
b. (y + x) · (z + y) + x · z · (z + z') = y + x · z
c. (y' · x) + x + (y + x) · y' = x + (y' · x)

Step 1

Step 1:** Apply the distributive law to the expression (x + y) + (y · x): (x + y) + (y · x) = x + y + y · x (x + y) + (y · x) = x + y + x · y (commutative property of multiplication) (x + y) + (y · x) = x + y (x · y = y · x in Boolean algebra) ** Show more…
