Question

Decide whether sets $A$ and $B$ are equal sets or not.$A=2,4,6,8$, $B$={x | x is a positive even natural number less than $9$}

Answer 1

$A=2,4,6,8$, $B$={x | x is a positive even natural number less than $9$}

$i.e.,B=\{2,4,6,8\}$

Since the elements in both sets area equal the sets are equal.
