# Simplification....at its worst.

Algebra Level 3

We all are very familiar with the simplification of $$\sqrt{a+b\pm2\sqrt{ab}}$$, which is $$\sqrt{a}\pm\sqrt{b}$$ (for $$a>b$$). But can you simplify this? $\sqrt{9-\sqrt{77}}$ Express your answer in the form of $$\sqrt{a}-\sqrt{b}$$, where $$a>b$$ and enter the value of $$2a+10b$$.
