The $3$3rd row of Pascal’s triangle contains the elements $1$1, $3$3, $3$3, $1$1. Each of these can be rewritten in $\nCr{n}{r}$`n``C``r` form: $\nCr{3}{0}$3`C`0, $\nCr{3}{1}$3`C`1, $\nCr{3}{2}$3`C`2, $\nCr{3}{3}$3`C`3.

Rewrite each element of the $5$5th row of Pascal’s triangle as an $\nCr{n}{r}$`n``C``r` coefficient.
