Answer 1

Объяснение:

а

$\sqrt{36} = 6 \\ \sqrt{0. 64} = 0. 8 \\ \sqrt{ \frac{1}{9} } = \frac{1}{3} \\ \sqrt{2500} = 50 \\ \sqrt{0.01} = 0.1 \\ \sqrt{0} = 0 \\ \sqrt{400} = 20$

б

$\sqrt{10000} = 100 \\ \sqrt{ \frac{81}{16} } = \frac{9}{4} \\ \sqrt{ \frac{1}{0.49} } = \frac{1}{0.7} \\ 10 \sqrt{0.04} = 10 \times 0.2 = 5 \\ - \sqrt{ \frac{4 .9}{12.1} } = - \sqrt{ \frac{ \frac{49}{10} }{ \frac{121}{10} } } = - \sqrt{ \frac{49}{121} } = - \frac{7}{11} \\ {( \sqrt{21.2}) }^{2} = 21.2$

с

$\sqrt{1.69} = 1.3 \\ \sqrt{2 \frac{1}{4} } = \sqrt{ \frac{2}{4} } = \frac{ \sqrt{2} }{2} \\ \sqrt{4 \frac{25}{36} } = 2 \frac{5}{6} = \frac{5}{3} = 1 \frac{2}{3} \\ \sqrt{ {( - 7)}^{2} } = \sqrt{49} = 7 \\ {( - \sqrt{0} )}^{2} = 0$
