Ответ:
\(\sqrt{72}\cdot\sqrt{2}=\sqrt{144}=12\).
\(\sqrt{45}\cdot\sqrt{5}=\sqrt{225}=15\).
\(\sqrt{360}\cdot\sqrt{490}=\sqrt{176400}=420\).
\(\sqrt{0.9}\cdot\sqrt{1.6}=\sqrt{1.44}=1.2\).
\(\frac{\sqrt{242}}{\sqrt{2}}=\sqrt{121}=11\).
\(\frac{\sqrt{40}}{\sqrt{0.025}}=\sqrt{\frac{40}{0.025}}=\sqrt{1600}=40\).
Ответ: 1) 12; 2) 15; 3) 420; 4) 1,2; 5) 11; 6) 40.
