ANSWER

- 7 \sqrt{6}

EXPLANATION

The given radical expression is

3 \sqrt{6}  - 10 \sqrt{2}  \times  \sqrt{3}

Recall and use

\sqrt{a}  \times  \sqrt{b}  =  \sqrt{ab}

to obtain;

3 \sqrt{6}  -10 \sqrt{2 \times 3}

Simplify the second radicand.

3 \sqrt{6}  - 10 \sqrt{6}

We have two like surds so we can simplify to obtain;

- 7 \sqrt{6}
