2.1
Demonstrate the validity of the following identities by means of truth tables:
(a) DeMorgan's theorem for three variables: (x + y + z)' = x'y'z' and (xyz)' = x' + y' + z'
(b) The distributive law: x + yz (x + y)(x + z)
(c) The distributive law: x(y + z) = xy + xz
(d) The associative law: x + (y + z) = (x + y) + z
(e) The associative law and x(yz) = (xy)z
2.2
Simplify the following Boolean expressions to a minimum number of literals:
(a)* xy + xy'
(c)* xyz + x'y + xyz'
(e) xyz' + x'yz + xyz + x'yz'
(b)* (x + y)(x + y')
(d)* (A + B)'(A' + B')'
(f) (x + y + z')(x' +y' + z)

Simplify the following Boolean expressions to a minimum number of literals:
(а)* АВС + A'В + АВС"
(c)* (x + y)'(x' + y')
(e)* (BC' + A'D)(AB' + CD')
(b)" x'yz + xz
