No, you can't do square roots and huge brackets with this. This will just render whatever glyphs are in a font. This is the best you can do for square root:

If you want stylized square roots and brackets like you would find in a program like Mathematica, you will have to render those yourself.
On the other hand, you could easily do the greek alphabet.
