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;

$- 7 \sqrt{6}$
