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

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

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

For any tow sets A and B(A-B)uu(B-A)=(A-B)uu Ab(B-A)uu Bc*(A uu B)-(A nn B)d(A uu B)nn(A nn B)

Applying the axiom of equality of two sets prove the identiti for any two sets A and B. A uu (A' nn B) = A uu B

Show that for any sets A and B A=(A nn B)uu(A-B) and quad A uu(B-A)=(A uu B)

Show that for any sets A and B, A = ( A nn B) uu ( A -B ) and A uu (B-A) = (A uu B)

Show that for any sets A and BA=(A nn B)uu(A-B) and A uu(B-A)=A uu B

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

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