Помогите решить, пожалуйста. Задание сверху на картинке

Answer 1

1) $5 \sqrt{2} = \sqrt{25 \times 2} = \sqrt{50}$

2) $7 \sqrt{3} = \sqrt{49 \times 3} = \sqrt{147}$

3) $0.3 \sqrt{6} = \sqrt{0.09 \times 6} = \sqrt{0.54}$

4) $\frac{1}{4} \sqrt{48} = \sqrt{ \frac{1}{16} \times 48 } = \sqrt{ \frac{48}{16} }$

5) $\frac{2}{9} \sqrt{162} = \sqrt{ \frac{4}{81} \times 162} = \sqrt{\frac{648}{81}}$

6) $- 2 \sqrt{10} = - \sqrt{4 \times 10 } = - \sqrt{40}$

7) $- 0.2 \sqrt{30} = - \sqrt{0.04 \times 30} = - \sqrt{1.2}$

8) $8 \sqrt{b} = \sqrt{64 \times b} = \sqrt{64b}$
