Question

If a is subset of b and b is subset of a then prove that a=b with proof

Answer 1

answer:

IF A SUBSET OF B IS A=(1,2,3) B=(1,2,3,4,5)

IF B SUBSET OF A IS A=(1,2,3,4,5) B=(1,2,3)

IF BOTH A SUBSET OF B AND B SUBSET OF A IS A=(1,2,3,4) B=(1,2,3,4)

THAT MEANS ALL THE ELEMENTS IN A MUST BE IN N

HENCE A=B

HENCE PROVED
