## boolean algebra proof [closed]

Hey guys,

I'm new at learning boolean algebra and understand the basic laws. But now I'm trying to proof:

x'z+ xyz + xy'z = z


Can someone help me with this please ?

Thanks in advance.

This question is not appropiate for MO, since it is not research level. The FAQ lists some websites that might be a better fit. Please try it at one of those. – Alberto García-Raboso Aug 13 2010 at 12:59
Am I right in thinking that this question should be closed? (Of course, this is not the fault of the questioner; it is easy to misunderstand the purpose of MathOverflow, especially if you are a newcomer.) You might be able to get an answer to this sort of question at the Wikipedia Mathematics Reference Desk. In fact, these questions are very much welcome there. Or, you could also see the Wikipedia article on Boolean algebras. – Amitesh Datta Aug 13 2010 at 14:14
