Question

Решите хотя-бы половины ​

Answer 1

1.

$\sqrt{0.49} = 0.7$

2.

$\sqrt[3]{64} = 4$

3.

$\sqrt[3]{ - 2 \frac{10}{27} } = \sqrt[3]{ - \frac{64}{27} } = - \frac{4}{3}$

4.

$0.5 \sqrt[4]{81} = 0.5 \times 3 = 1.5$

5.

$\sqrt[4]{ \frac{81}{16} } + \sqrt[3]{ - \frac{1}{27} } = \frac{3}{2} - \frac{1}{3} = \frac{9}{6} - \frac{2}{6} = \frac{7}{6}$

6.

$(2 \sqrt[3]{6} )^{3} = {2}^{3} \times \sqrt[3]{ {6}^{3} } = 8 \times 6 = 48$

7.

$\frac{6}{(3 \sqrt{2})^{2} } = \frac{6}{9 \times 2} = \frac{6}{18} = \frac{1}{3}$

8.

$- 3 \sqrt[3]{( - 6)^{3} } = - 3 \times ( - 6 )= 18$

9.

$\sqrt[4]{81} \times \sqrt[3]{8} = 3 \times 2 = 6$

10.

$\sqrt[43]{1} \times \sqrt[3]{ - 0.125} = 1 \times - 0.5 = - 0.5$

11.

$\sqrt[5]{27} \times \sqrt[5]{9} = \sqrt[5]{27 \times 9} = \sqrt[5]{243} = 3$

12.

$\sqrt[4]{9} \times \sqrt[4]{18} \times \sqrt[4]{8} = \sqrt[4]{9 \times 18 \times 8} = \sqrt[4]{1296} = 6$

13.

$\frac{ \sqrt[3]{500} }{5 \sqrt[3]{4} } = \frac{ \sqrt[3]{125} }{5} = \frac{5}{5} = 1$
