sqrt(337) ~~ 18.35755975 is not simplifiable since 337 is prime.

Explanation:

337 is prime - it has no positive factors apart from 1 and itself.

As a result, sqrt(337) is not simplifiable.

It is an irrational number which when squared (multiplied by itself) gives you 337. Its value is approximately 18.35755975.

Since it is irrational, its decimal representation neither terminates nor recurs.

It has a continued fraction expansion which does repeat, namely:

sqrt(337) = [18;bar(2,1,3,1,11,2,4,1,3,3,1,4,2,11,1,3,1,2,36)]

=18+1/(2+1/(1+1/(3+1/(1+1/(11+1/(2+1/(4+1/(1+...))))))))

To construct rational approximations for sqrt(337) you can truncate this continued fraction.

For example:

sqrt(337) ~~ [18;2,1,3,1] = 18+1/(2+1/(1+1/(3+1/1))) = 257/14 ~~ 18.357
