# How do you simplify -35sqrt(-sqrt6-sqrt5)?

The value is undefined.

#### Explanation:

If we take a look at the expression, we can simplify it a little bit:

$\textcolor{w h i t e}{=} - 35 \sqrt{- \sqrt{6} - \sqrt{5}}$

$= - 35 \sqrt{\textcolor{red}{- 1} \setminus \cdot \sqrt{6} + \textcolor{red}{- 1} \cdot \sqrt{5}}$

$= - 35 \sqrt{\textcolor{red}{- 1} \setminus \cdot \left(\sqrt{6} + \sqrt{5}\right)}$

$= - 35 \sqrt{\textcolor{red}{-} \left(\sqrt{6} + \sqrt{5}\right)}$

Now, we can see that the part that is under the bigger radical is a negative number (it's about $- 4.6856$), so that means that the radical is undefined.

Therefore, the whole expression is undefined. Hope this helped!
