\[\boxed{\mathbf{898\ (898).\ }Еуроки\ - \ ДЗ\ без\ мороки}\]

\[1)\ \sqrt{24} = 2\sqrt{6}\]

\[2)\ \sqrt{63} = 3\sqrt{7}\]

\[3)\ \sqrt{700} = 10\sqrt{7}\]

\[4)\ \sqrt{0,32} = 0,4\sqrt{2}\]

\[5)\ \frac{1}{7}\sqrt{196} = \frac{1}{7} \cdot 14 = 2\]

\[6) - 2,4\sqrt{600} = - 2,4 \cdot 10\sqrt{6} =\]

\[= - 24\sqrt{6}\]

\[7) - 1,6\sqrt{50} = - 1,6 \cdot 5\sqrt{2} =\]

\[= - 8\sqrt{2}\]

\[8)\ \frac{5}{8}\sqrt{3\frac{21}{25}} = \frac{5}{8}\sqrt{\frac{96}{25}} = \frac{5}{8} \cdot \frac{4\sqrt{6}}{5} =\]

\[= \frac{\sqrt{6}}{2} = \frac{1}{2}\sqrt{6}\]
