It looks like you've input part of an expression:

$\sqrt{3} \left( \sqrt{5 - \sqrt{6}} \right)$

Is this the expression you want help simplifying, or are you looking for something else? Let me know if you'd like assistance solving this or working through its steps!

Would you like to explore the steps involved in simplifying it? Here's how we can approach:

1. First, break down the inner square root: $\sqrt{5 - \sqrt{6}}$.
2. Look for potential rational approximations or simplifications within the nested radical.
3. Multiply the result by $\sqrt{3}$ once the inner radical is simplified.

Feel free to ask for further details or clarification!
