Question: How to simplify this simple expression (best)?

is a typical example of Maple output (in this case the natural frequency of a harmonic oscillator with m>0) where further simplification to text book notation is desired.

To get

the context menu did not help. On the command level, combine,radical (which I assumed is suitable) was also not effective.

Is there a better way to achieve the desired simplification than the one (found by trial and error) in the attachment?

If there is no better way: Would it make sense to improve the combine or any other command for such a case?
