Applying RootReduce to the difference of the left-hand side and the
right-hand side returns 0.

Applying RootReduce to the right-hand side followed by ToRadicals gives the
left-hand side.

The first technique is more general.

I have some question about the mathematica commands.
I know that \sqrt{3+2 \sqrt{3}} = 3^{1/4}*(1+\sqrt{3})/\sqrt{2}.
Then how one can get this result from Mathematica? Which command I
should use in order to
get the right hand side in the above expression?
