The best way is to use a calculator, and \(\sqrt {361}\) is \(19\).

 

You are very welcome!

:P

Also, to cover the \(361\) completely with the square root radical, \(\sqrt{361}\) = \sqrt{361}

Or, you can list the first few squares out. If you know \(20^2=400\), ‚Äč\(19^2=381. \)

That's what I said. Just trying to list a few squares out, to find the answer.

REMEMBER:
sqrt361 =  + or - 19
