10. Let A and B be subsets of Rn.

(a) Show that 8(A n B) n (AC U (8B)C) ~ 8A.

(b) Show that if x E 8(A n B) and x tI. (A n 8B) U (B n 8A), then x E 8A n 8E.

(c) Prove that 8(A n B) ~ (A n 8B) U (B n 8A) U (8A n 8B).

(d) Show that even in R, there exist sets A and B such that 8(A n B) #- (A n 8B) U (B n 8A) U (8A n 8B).
