          Question 1 (30 pts): Use algebraic manipulation to prove the following Boolean statements.
a) Combining laws:
a-1): $(x + y) \cdot (x + \bar{y}) = x$
a-2): $x \cdot y + x \cdot \bar{y} = x$
b) $x_1x_2 + x_1\bar{x_2} + \bar{x_1}x_2 = x_1 + x_2$
c) $(x_1 + x_2 + x_3 + x_4)(x_1 + x_2 + x_3 + \bar{x_4}) = x_1 + x_2 + x_3$
d) (Bonus 5 pts) $xy + yz + \bar{x}z = xy + x\bar{z}$

Question 1 (30 pts): Use algebraic manipulation to prove the following Boolean statements.
a) Combining laws:
a-1): (x + y) · (x + y̅) = x
a-2): x · y + x ·y̅ = x
b) x1x2 + x1x̅2̅ + x̅1̅x2 = x1 + x2
c) (x1 + x2 + x3 + x4)(x1 + x2 + x3 + x̅4̅) = x1 + x2 + x3
d) (Bonus 5 pts) xy + yz + x̅z = xy + xz̅

Step 1

a-1: Starting with the left-hand side of the equation: x + yx + y We can factor out an x: x(1 + y) + y Using the identity 1 + y = 1, we can simplify: x(1) + y Which is just x + y, the right-hand side of the equation. Show more…
