Grouping terms under the radical

This must be a classic question. When I input Sqrt[(2 n)] Mathematica displays the output as Sqrt[2] Sqrt[n] -- i.e., both 2 and n are under their own radical. The display of output doesn't change if I impose the assumption that n > 0. This is fine from a mathematical point of view, but it looks unconventional when pasted into a paper. It seems to me most authors would keep the 2 and the n under a common radical -- how can I get Mathematica to do the same? Thanks!
