(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

prove the following:A U (intersect from i = 1 to n of Bi) = intersect of i from 1 to n of (A U B)

2. Relevant equations

3. The attempt at a solution

i started off trying to rewrite it and make it a bit more readable

A U (Bi and Bi+1) = Bi+1 and (A U Bi)

then i was going to expand them and write the outcomes and show that they have the same as the proof

for the first part i got: AA ABi ABi+1 and both Bs

my problem is that i think i messed up the right hand side when rewriting it because that way the most i can get is 2 outcomes

any thoughts?
