1,3 срочно нужно пожалуйста!!!

Answer 1

1
$10 \times \frac{1}{25} - \frac{7}{10} = \frac{10}{25} - \frac{7}{10} = \frac{2}{10} - \frac{7}{10} = - \frac{5}{10} = - 0.5$

3
$\frac{ \sqrt{24} \times \sqrt{3}^{2} }{ \sqrt{2} } = (\frac{ \sqrt{24} \times \sqrt{3}^{2} }{ \sqrt{2} } )^{2} = \frac{24 \times 729}{2} = 12 \times 729 = 8748$
