Hi friends....I m Faizan Ahmed, doing BS Maths from uni of Sindh...
I've been given the following assignment:
(1) (UAi iEI) n (UBj jEJ) = U {Ai n Bj , : iEI, jEJ}
(2) A - (UBi iEI) = n iEI (A - Bi)
(3) A - (nBi iEI) = U iEI (A - Bi)
(4) U iEI Ai - UBi iEI subset U iEI (Ai - Bi)
We have to prove all of these w/o supposing any element.
Could any 1 of u plz help me.........?
U=Union
n=intersection
E=belongs to
