X is a size 8 set formed by 1,2,3,4,5
We define relation $R$ on X such that, $xRy$$\Leftrightarrow $ $x$ and $y$ sets formed from same numbers and same amount of each kind. We know the relation $R$ is already an equivalence relation
an example:
How I can approach this question? knowing there are $8^5$ possible ways to form set x,y that belong to X
