For all sets a,B and C show that `(A-B)nn(A-C)=A-(BuuC)`

For sets A,B and C, prove that : (A-B)nn C=(A nn C)-B .

For sets A,B and C, prove that : A-(B-C)=(A-B) uu(A nn C) .

For sets A,B and C, prove that : A-(B uu C)=(A-B) nn (A-C) .

Applying the properties of sets prove the identity for any three sets A, B and C. A-(B nn C)=(A-B) uu (A-C)

For any sets A, B, C, D , prove that: (AxxB)nn (CxxD)=(A nn C)xx(B nn D) .

For all sets A and B, (A - B) uu (A nn B) = A .

For all sets A and B, (A - B) uu (A nn B) = A .

Theorem 8( For any set A;B and C prove that A xx(B'uu C')'=(A xx B)nn(A xx C)

For any sets A,B,C,D prove that: (A xx B)nn(C xx D)=(A nn C)xx(B nn D)
