Show that: (a) n∪i=1 Ai is closed if all Ai the are;

b) ∩i∈∧ Ai

is closed if all the Ai are;

c) ∞∩i=1 ki

is not empty if the Ki are non empty closed intervals in R and

Ki ⊇ Ki+1 for all i ≥ 1. (Ai ⊆ Rm for all i).

answer: the answer is simply nothing.

step-by-step explanation: because there is no ending to this question
