Question

Найди значение выражения с 6 до 10

Answer 1

$6) \sqrt{10} \times \sqrt{3.6} = \sqrt{10 \times 3.6} = \sqrt{36} =6\\ 7) \frac{5}{14} \sqrt{28} \times \sqrt{63} = \frac{5}{14} \times 2 \sqrt{7} \times 3 \sqrt{7} = \frac{5}{7} \times 7 \times 3 = 5 \times 3 = 15 \\ 8) \sqrt{7 \times 18} \times \sqrt{42} = \sqrt{5292} = 42 \sqrt{3} \\ 9) \frac{ \sqrt{42 \times 119} }{ \sqrt{17 \times 6} } = \frac{ \sqrt{4998} }{ \sqrt{102} } = \frac{7 \sqrt{102} }{ \sqrt{102} } = 7 \\ 10)( \sqrt{20} - \sqrt{5} ) \sqrt{5} = (2 \sqrt{5} - \sqrt{5} ) \sqrt{5} = \sqrt{25} = 5$
