prove that a) (x1 + x2 + ・ ・ ・ + xn) _ x1x2 ・ ・ ・ xn Assume the result for n _ k (≥ 2) and consider the case of n _ k + 1. b) (x1x2 ・ ・ ・ xn) _ x1 + x2 + ・ ・ ・ + xn Follows from part (a) by duality. 5. Let_be a Boolean algebra that is partially ordered by≤. If x, y, z ∈ _, prove that x + y ≤ z if and only if x ≤ z and y ≤ z. If x ≤ z and y ≤ z, then from Exercise 6(b) of Section 15.4 we have x + y ≤ z + z. z + z _ z. Conversely, suppose that x + y ≤ z.We find that
