## Homework Statement

Prove the following through boolean algebra

x’y’z’ + xy’z + x’yz’ + xyz + xyz’ = x’z’ + yz’ + xz

x’y’w + x’yw + x’yzw’ = x’w + x’yz

xy’z + x’y’z + xyz

## The Attempt at a Solution

Well i start by using the commutative law on the first one.

x’y’z’ + xyz + xy’z + x’yz' + xyz’ = x’z’ + yz’ + xz

At first i thought x’y’z’ + xyz might be something i can simplify, however it doesn't look like there are any boolean identities i can use on that.

With the second and third equivalency, i don't even know where to start. :/
