2) √0,72/8

Answer 1

Ответ:

$1) \sqrt{ 2.5} \times \sqrt{10} = \sqrt{25} = 5 \\ 2) \sqrt{ \frac{0.72}{8} } = \sqrt{ \frac{72}{800} } = \sqrt{ \frac{36}{400} } = \frac{6}{20} = \\ = \frac{3}{10}$

Answer 2

1)

$\sqrt{25} = 5$

2)

$\sqrt{0.72} \div 8 = \frac{ \sqrt{72} }{8} = \frac{2 \sqrt{18} }{8} = \frac{ \sqrt{18} }{4} = \frac{3 \sqrt{2} }{4} = 0.75 \sqrt{2}$
