In the following,state whether $A=B$ or not:
$A=\{a, b, c, d\} ; B=\{d, c, b, a\}$
$A=\{a, b, c, d\} ; B=\{d, c, b, a\}$
(A) $A=\{a, b, c, d\}$
$B=\{d, c, b, a\}$
The order in which the elements of a set are listed is not significant.
Since both sets contain the exact same elements,$\therefore A=B$.
