96. Вынесите множитель из-под знака корня:
1) $$ \sqrt{56} = \sqrt{4 \cdot 14} = 2\sqrt{14} $$
2) $$ \sqrt{18} = \sqrt{9 \cdot 2} = 3\sqrt{2} $$
3) $$ \sqrt{800} = \sqrt{400 \cdot 2} = 20\sqrt{2} $$
4) $$ \sqrt{0.96} = \sqrt{\frac{96}{100}} = \sqrt{\frac{16 \cdot 6}{100}} = \frac{4\sqrt{6}}{10} = \frac{2\sqrt{6}}{5} $$
5) $$ \frac{1}{3}\sqrt{90} = \frac{1}{3}\sqrt{9 \cdot 10} = \frac{1}{3} \cdot 3\sqrt{10} = \sqrt{10} $$
6) $$ -1.5\sqrt{192} = -1.5\sqrt{64 \cdot 3} = -1.5 \cdot 8\sqrt{3} = -12\sqrt{3} $$
7) $$-7\sqrt{0.12} = -7\sqrt{\frac{12}{100}} = -7\sqrt{\frac{4 \cdot 3}{100}} = -7 \cdot \frac{2\sqrt{3}}{10} = -\frac{7\sqrt{3}}{5} $$
8) $$ \frac{3}{7}\sqrt{10\frac{8}{9}} = \frac{3}{7}\sqrt{\frac{98}{9}} = \frac{3}{7}\sqrt{\frac{49 \cdot 2}{9}} = \frac{3}{7} \cdot \frac{7\sqrt{2}}{3} = \sqrt{2} $$
Ответ: 1) $$2\sqrt{14}$$; 2) $$3\sqrt{2}$$; 3) $$20\sqrt{2}$$; 4) $$\frac{2\sqrt{6}}{5}$$; 5) $$\sqrt{10}$$; 6) $$-12\sqrt{3}$$; 7) $$\frac{-7\sqrt{3}}{5}$$; 8) $$\sqrt{2}$$
