Just started up on my new logic gates module and wondering if anyone could give me a little feedback and assistance,

I got a Boolean equation to simplify

( A . B + A . B . C + A . B . C . D + A . B . C . D . E + A . B . C . D . E .F)

The . is an AND

The + is an OR

I got; A.B.C.D.E.F

Am I completely wrong or doing it right? Just wondering so in future I don't make mistakes, sorry for such a newbie question If it's wrong could anybody tell me how I would go about doing it correctly?

I got also a truth table to work out,

I really have no idea how to approach the truth table, I need to work out X, though I'm not asking for anybody to do it for me, just how will I go about working it out?
