Question

proof that (A-B)U(B-A)=(AUB)-(AnB)​

Answer 1

hey mate here your answer

Answer 2

SOLUTION

=let A={1,2,3,4,5} B={1,2,3,6}

According to the question

TO PROVE=(A-B)U(B-A)=(AUB)-(AnB)✔✔

PROOF÷solving both the eqautions LHS

LHS

(A-B)U(B-A)

{4,5}U{6}

{4,5,6}

RHS

(AUB)-(AnB)

{1,2,3,4,5,6}-{1,2,3}

{4,5,6}

LHS=RHS✔✔

Therefore,(A-B)U(B-A)=(AUB)-(AnB) PROVED
