Answer 2

Объяснение:

$1. \: 1) \sqrt{9 \times 36} = \sqrt{9} \times \sqrt{36} = 3 \times 6 = 18$

$2) \sqrt{ 3\frac{1}{16} } = \sqrt{ \frac{49}{16} } = \frac{ \sqrt{49} }{ \sqrt{16} } = \frac{7}{4} = 1 \frac{3}{4}$

$3) \sqrt{13^{2} } = 13$

$4)( 3 \sqrt{2} )^{2} = ( \sqrt{18} )^{2} = 18$

$2. \: 1) \sqrt{3} \times \sqrt{27} = \sqrt{3 \times 27} = \sqrt{81} = 9$

$2) \frac{ \sqrt{500} }{ \sqrt{5} } = \sqrt{ \frac{500}{5} } = \sqrt{100} = 10$

$3. \: 1) {x}^{2} = 64 \\ x = \sqrt{64} \\ x = 8$

$2)3x^{2} - 21 = 0 \\3 {x}^{2} = 21 \\ {x}^{2} = 21 \div 3 \\ {x}^{2} = 7 \\ x = \sqrt{7}$

$4. \: 1) \sqrt{0.01 \times 2.25 } = \sqrt{0.01} \times \sqrt{2.25} = 0.1 \times 1.5 = 0.15$

$2) \sqrt{4 \frac{33}{64} } = \sqrt{ \frac{289}{64} } = \frac{ \sqrt{289} }{ \sqrt{64} } = \frac{17}{8} = 2 \frac{1}{8}$

$3)2 \sqrt{( - 17)^{2} } = 2 \times 17 = 34$

$4)7 \sqrt{3} \times ( - \sqrt{3) } = 7 \times ( - 3) = - 21$

$5. \: 1) \frac{ \sqrt{26} }{ \sqrt{104} } = \sqrt{ \frac{26}{104} } = \sqrt{ \frac{1}{4} } = \frac{1}{2}$

$2) \sqrt{7^{4} \times 2 ^{5} } \times \sqrt{2} = 392$

$6. \: 1) \frac{4}{ \sqrt{5 \frac{11}{49} } } = \frac{4}{ \sqrt{ \frac{256}{49} } } = \frac{4}{ \frac{ \sqrt{256} }{ \sqrt{49} } } = \frac{4}{ \frac{16}{7} } = 4 \div \frac{16}{7} = \frac{4}{1} \times \frac{7}{16} = \frac{1}{1} \times \frac{7}{4} = \frac{7}{4} = 1 \frac{3}{4}$

$2) \sqrt{1 \frac{8}{27} } \times \sqrt{7} \times \sqrt{ \frac{3}{5} } = \sqrt{ \frac{35}{27} \times \frac{7}{1} \times \frac{3}{5} } = \sqrt{ \frac{7}{9} \times \frac{7}{1} \times \frac{1}{1} } = \sqrt{ \frac{49}{9} } = \frac{ \sqrt{49} }{ \sqrt{9} } = \frac{7}{3} = 2 \frac{1}{3}$
