Ответ:
- \(\sqrt{2}\cdot\sqrt{8}=\sqrt{16}=4\).
- \(\sqrt{1000}=\sqrt{100\cdot10}=10\sqrt{10}\).
- \(\sqrt{5}\cdot\sqrt{5}=5\).
- \(\sqrt{0{,}36}=0{,}6\), так как \(0{,}6^2=0{,}36\).
- \((4\sqrt{7})^2=4^2\cdot(\sqrt{7})^2=16\cdot7=112\).
- \(\sqrt{360}=\sqrt{36\cdot10}=6\sqrt{10}\).
- \(\sqrt{25-9}=\sqrt{16}=4\).
- \(\sqrt{25\cdot9}=\sqrt{225}=15\).
