Answer 3

@shubhamsrg, I think it might be a topology question: http://en.wikipedia.org/wiki/Interior_(topology)
You have to show that
\[\mbox{int}A\cap\mbox{int}B=\mbox{int}(A\cap B)\]
I haven't taken topology before, so I doubt I can be of any help. I'll see if I can get an idea from the wiki page.

Answer 4

thx yep its topology
