M-m s in math mode gives a _s_quare root, M-m r an n-th root.
Unfortunately, there's no clickable button associated with it.

You should have a look at the \include-Features in the Insert-Menu.
Read the "Extended Features" document that you can reach under the Help
menu, chapter 1.5 deals with multipart documents...

That's exactly what's happening now, at least with LyX-1.0.4

The only problem left is inserting cross-references that are not
originated in the current document. This one's a bit tricky but not
unsolveable. Ask me, if you have problems with it.

In the above mentioned "Extended Features" document section 1.9.2 deals
with minipages. There are handled a bit more complicated than you
described above, but it works. Sure, the WYSIWYM layout is not that
"clear" as with eps-files which is due to the fact, that LyX does not
know how the minipage will look like in Real World (TM), before it has
been rendered by LaTeX. With eps files this step is done via Ghostscript
in a background process, so LyX DOES know about the appearance of the
eps file.

Future enhancements could---perhaps?---render the minipage seperately
(is that really possible with LaTeX?) and insert the resulting dvi-file
(better: eps-file) in a LyX environment similar to included eps-files.
But that are dreams of the future!

...yeah, but---please---read the documentation before asking! Thanks...
