You can put this solution on YOUR website!
13%5E2=169, starting from rational, ending in the computed value.
sqrt%28169%29=13


sqrt%280.4049586776859%29, but so that is not finished being expressed...;
sqrt%280.4049586776859%29=sqrt%28%287%2F11%29%5E2%29=7%2F11
and 7%2F11 is too, a rational number.


These are just examples. You can find many, many more.
