The expression you provided is:

$2 \sqrt{3} + \sqrt{5}$

This is a simplified form already, since $\sqrt{3}$ and $\sqrt{5}$ are irrational numbers and cannot be simplified further.

So the final expression is:

$2 \sqrt{3} + \sqrt{5}$

If you would like an approximate decimal value, I can calculate it for you. Would you like to see that?

Tip: Remember that square roots of non-perfect squares are often left in their simplest form, unless approximations are needed.
