The distributive rule
(x + yz) = (x + y) • (x + z), we can start by expanding the right side of the equation using the distributive property.
(x + y) • (x + z) = x(x + z) + y(x + z)

Now, we can further simplify this expression by applying the distributive property again.
= x^2 + xz + xy + yz Notice that the terms
xz and xy + yz are the same as the terms in the left side of the equation (x + yz). Therefore, we can conclude that
x + yz = (x + y) • (x + z), which proves the distributive rule.

To prove the consensus property, we need to show that
(x + y)(x + y') = x. Using the distributive property, we can expand the left side of the equation.
(x + y)(x + y') = x(x + y') + y(x + y') Next, we can simplify this expression by applying the distributive property again.
= x^2 + xy' + xy + yy'

Now, notice that xy' + xy is equal to x(y' + y), and since y' + y equals 1 (based on the consensus property), we can simplify the expression further.
= x^2 + x(1) + yy'Finally, we can simplify this expression even more by recognizing that x(1) equals x, and yy' equals 0.
= x + 0

Thus, we have shown that
(x + y)(x + y') = x,which proves the consensus property. (Explanation for the third question is missing) . (Explanation for the fourth question is missing) I apologize, but it seems that the explanations for the third and fourth questions are missing from your request.
