Ответ:
- \(\sqrt{9\cdot36}=\sqrt{9}\cdot\sqrt{36}=3\cdot6=18\).
- \(\sqrt{25\cdot81}=5\cdot9=45\).
- \(\sqrt{16\cdot900}=4\cdot30=120\).
- \(\sqrt{2500\cdot49}=50\cdot7=350\).
- \(\sqrt{0.64\cdot25}=0.8\cdot5=4\).
- \(\sqrt{0.49\cdot16}=0.7\cdot4=2.8\).
- \(\sqrt{0.09\cdot0.25}=0.3\cdot0.5=0.15\).
- \(\sqrt{0.36\cdot1.44}=0.6\cdot1.2=0.72\).
