I think that I have shown you how to do TaTeX.
[TEX]2\sqrt{3}+3\sqrt{27}[/TEX] gives $2\sqrt{3}+3\sqrt{27}$.

Note that $3\sqrt{27}=9\sqrt{3}$ because $\sqrt{27}=\sqrt{9\cdot 3}$

thanks for answering, so would it be $2\sqrt{3}+9\sqrt{3}$ ??

If you have two apple and nine apples how many apples do you have?
