Question 475556: what is the square root of 210 simplified?

sqrt%28210%29+=+sqrt%282%2A105%29+=+sqrt%282%2A5%2A21%29+=+sqrt%282%2A5%2A3%2A7%29

That shows that 210 is not divisible by any perfect square factors
(except 1).  Therefore sqrt%28210%29 cannot be simplified
further.  You just have to leave it sqrt%28210%29, which is its
simplest radical form, or else approximate it with a decimal using
a calculator as 14.49137675.
