Answer 2

Respuesta:

$\sqrt[3]{ \frac{1}{2} + 0.3 + 0.2 {}^{2} } - (0.7 + 1.72) {}^{ - 2} \\ \sqrt[3]{ \frac{1}{2} + \frac{3}{10} + \frac{2}{10} } - ( \frac{7}{9} + \frac{31}{18} ) { }^{ - 2} \\ \sqrt[3]{ \frac{5}{10} + \frac{3}{10} + \frac{2}{10} } - ( \frac{14}{18} - \frac{31}{18} ) {}^{ - 2} \\ \sqrt[3]{ \frac{10}{10} } - ( \frac{45}{18} ) {}^{ - 2} \\ \sqrt[3]{1} - (( \frac{45}{18} ) { }^{ - 1} ) {}^{2} \\ 1 - ( \frac{18}{45} ) {}^{2} \\ 1 - \frac{4}{25} = \frac{25}{25} - \frac{4}{25} = \frac{21}{25}$

$\frac{1}{2} \times \frac{5}{5} = \frac{5}{10} \\ \frac{7}{9} \times \frac{2}{2} = \frac{14}{18} \\ 0.3 \times \frac{10}{10} = \frac{3}{10} \\ 0.2 \times \frac{10}{10} = \frac{2}{10} \\ n = 0.7 \\ 10n = 7.7 \\ 10n - n = 7.7 - 0.7 \\ 9n = 7 \\ n = \frac{7}{9} \\ n = 1.72 \\ 10n = 17.2 \\ 100n = 172.2 \\ 100n - 10n = 172.2 - 17.2 \\ 90n = 155 \\ n = \frac{155}{90} = \frac{31}{18}$

$( \frac{18}{45 } ) {}^{2} = \frac{18 {}^{2} }{{45}^{2} } = \frac{324}{2025} = \frac{4}{5}$
