Ответ:
- \(\sqrt{9\cdot64\cdot0.25}=\sqrt{144}=12\).
- \(\sqrt{0.09\cdot16\cdot0.04}=\sqrt{0.0576}=0.24\).
- \(\sqrt{\frac{25}{81}\cdot\frac{16}{49}\cdot\frac{196}{9}}=\frac{5}{9}\cdot\frac{4}{7}\cdot\frac{14}{3}=\frac{40}{27}\).
- \(\sqrt{\frac{121}{144}\cdot2\frac{1}{4}}=\sqrt{\frac{121}{144}\cdot\frac{9}{4}}=\sqrt{\frac{1089}{576}}=\frac{11}{8}\).
- \(\sqrt{810\cdot40}=\sqrt{32400}=180\).
- \(\sqrt{10\cdot250}=\sqrt{2500}=50\).
- \(\sqrt{72\cdot32}=\sqrt{2304}=48\).
- \(\sqrt{8\cdot98}=\sqrt{784}=28\).
- \(\sqrt{10}\cdot\sqrt{40}=\sqrt{400}=20\).
- \(\sqrt{12}\cdot\sqrt{3}=\sqrt{36}=6\).
- \(\sqrt{\frac{2}{3}}\cdot\sqrt{\frac{3}{8}}=\sqrt{\frac{1}{4}}=\frac{1}{2}\).
- \(\sqrt{1\frac{4}{5}}\cdot\sqrt{0.2}=\sqrt{\frac{9}{5}}\cdot\sqrt{\frac{1}{5}}=\sqrt{\frac{9}{25}}=\frac{3}{5}\).
