Question

what is the symbol of row in sets?​

Answer 1

Answer:

Show that A UB=An B implies A = B

In order to prove A = B, we should prove

A is a subset of B i.e. A CB

& B is a subset of A i.e. B CA

Let x E A.

Then, x E AUB.

Since A UB=AnB,

XEAN B.So, x E B... If x EA, then x E B

i.e. if an elements belongs to set A, then it must belong to set B also

Therefore, ACB.

Similarly, if y E B,

then y EAU B.

Since A UB=An B,

YEAN B.

So, y E A.

.. If y EB, then y EA i.e. if an elements belongs to set B, then it must belong to set A also Therefore, BCA.
