Hello,

I'm trying to solve Boolean Algebra Problem . And here's it

Prove that X'Y'Z' + X'YZ + XY'Z + XYZ' = (X xor Y)' xor Z

I've proofed that

this problem = (X Xor Y xor Z)' but i can't get that one above . Can anybody help,please?

That's not the point- you posted the same thing twice in the same forum!

(But you should still not post the same thing even in different forums.)

The standard place for such problems is the Discrete Mathematics subforum.
