Answer 2

Объяснение:

$\frac{1}{8} \sqrt{0.64} - 1 = 0.125 \times 0.8 - 1 = 0.1 - 1 = - 0.9 = - \frac{9}{10}$

$1) \sqrt{16} = \sqrt{ {4}^{2} } \\ 2) \sqrt{100} = \sqrt{ {10}^{2} } = 10 \\ 3) \sqrt{49} = \sqrt{ {7}^{2} } = 7 \\ 4) \sqrt{81} = \sqrt{ {9}^{2} } = 9$

$1) \sqrt{0.25} = \sqrt{ {0.5}^{2} } = 0.5 \\ 2) \sqrt{3600} = \sqrt{ {60}^{2} } = 60 \\ 3) \sqrt{0.09} = \sqrt{ {0.3}^{2} } = 0.3 \\ 4) \sqrt{400 } = \sqrt{ {20}^{2} } = 20$
