HW6.3 assianed: For the following two Boolean expressions, simplify as much as possible: A. xyz' + xyz + xyz + xyz' B. xyzt + xyt + xyz't + yzt C. Prove: [Hint: On the left side, expand the term yz, by trying to introduce the x- variable as in multiplying by 1x +x' then apply absorption] Hint HW 6.3 Use Axioms Properties as much as possible, especially group terms and use 4): xyz' + xyz + xyz + xyz' = xy(2 + z') + x'y(2+z)
