Can you add a radical with a whole number #4 + 2sqrt3#?

No, you can't.

You can't even add different radicals, like #sqrt2+sqrt3# and if the radicals are of different power, you can't even add those, so

#sqrt2+root3 2# stays as is.

The most you can do with your example is take the #2# 'out of the brackets', but only if that's useful for further calculations, like:

#4+2sqrt3=2*(2+sqrt3)#
