Need all questions solved on paper.

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
