Внесите множитель под знак корня:
1) $2\sqrt{6}$;
2) $9\sqrt{2}$;
3) $-11\sqrt{3}$;
4) $12\sqrt{b}$;
5) $-7\sqrt{3c}$;
6) $-10\sqrt{0,7m}$;
7) $8\sqrt{\frac{n}{8}}$;
8) $-\frac{1}{3}\sqrt{18p}$.
$2\sqrt{6} = \sqrt{2^2} * \sqrt{6} = \sqrt{4} * \sqrt{6} = \sqrt{4 * 6} = \sqrt{24}$
$9\sqrt{2} = \sqrt{9^2} * \sqrt{2} = \sqrt{81} * \sqrt{2} = \sqrt{81 * 2} = \sqrt{162}$
$-11\sqrt{3} = -\sqrt{11^2} * \sqrt{3} = -\sqrt{121} * \sqrt{3} = -\sqrt{121 * 3} = -\sqrt{363}$
$12\sqrt{b} = \sqrt{12^2} * \sqrt{b} = \sqrt{144} * \sqrt{b} = \sqrt{144b}$
$-7\sqrt{3c} = -\sqrt{7^2} * \sqrt{3c} = -\sqrt{49} * \sqrt{3c} = -\sqrt{49 * 3c} = -\sqrt{147c}$
$-10\sqrt{0,7m} = -\sqrt{10^2} * \sqrt{0,7m} = -\sqrt{100} * \sqrt{0,7m} = -\sqrt{100 * 0,7m} = -\sqrt{70m}$
$8\sqrt{\frac{n}{8}} = \sqrt{8^2} * \sqrt{\frac{n}{8}} = \sqrt{64} * \sqrt{\frac{n}{8}} = \sqrt{64 * \frac{n}{8}} = \sqrt{8n}$
$-\frac{1}{3}\sqrt{18p} = -\sqrt{(\frac{1}{3})^2} * \sqrt{18p} = -\sqrt{\frac{1}{9}} * \sqrt{18p} = -\sqrt{\frac{1}{9} * 18p} = -\sqrt{2p}$
