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