$sqrt6561=81$

Explanation:

To find square root of $6561$ , we should first factorize it.

From divisibility rules, it is apparent that it is divisible by $3$ and dividing by $3$ , we get $2187$ , which is again divisible by $3$ and dividing by $3$ , we get $729$ .

$729$ is clearly again divisible by $3$ . Dividing by $3$ , we get $243$ , which is again divisible by $3$ and dividing it by $3$ we get $81$ , which is clearly $3xx3xx3xx3$ .

Hence, $6561=3xx3xx3xx3xx3xx3xx3xx3$ and hence

$sqrt6561=sqrt(bar(3xx3)xxbar(3xx3)xxbar(3xx3)xxbar(3xx3))$

= $3xx3xx3xx3=81$
