EX| Prove the relation is true :
x y + xy = x y + x y
SOL\
Right hand side (RHS):-
x y +xy = x y.xy
DeMorgan's Theorem
= =
= (x +y) (x+y)
Rule 9: x = x
= (x+y) (x+y)
Factoring (distributive law)
= xx + xy + y x + yy
Rule 8: xx = 0, y y= 0
= x y + y x
Therefore the relation is true
Leſt hand side (LHS):-
x y + xy = xy. x y
Factoring (distributive law)
DeMorgan's Theorem
= (x + y) (x + y)
Rule 9: x = x
= (x+y) (x + y)
Factoring (distributive law)
= xx + x y + y x + yy
Rule 8: xx = 0, y y= 0
= x y + y x
Therefore the relation is true
