Упрости выражение:

1. \(\sqrt{81a}+\sqrt{16a}-\sqrt{121a}=9\sqrt{a}+4\sqrt{a}-11\sqrt{a}=\) [ ];

2. \(\sqrt{100c}-\sqrt{400c}+\sqrt{900c}=\) [ ];

3. \(\sqrt{45}+\sqrt{80}-\sqrt{500}=\sqrt{9\cdot 5}+\sqrt{16\cdot 5}-\sqrt{100\cdot 5}=\) [ ];

4. \(\sqrt{8}+\sqrt{50}-\sqrt{18}=\) [ ];

5. \(\sqrt{150p}-\sqrt{54p}+\sqrt{24p}=\sqrt{25\cdot 6p}-\sqrt{9\cdot 6p}+\) [ ] \(=\) [ ];

6. \(\sqrt{396m}+2\sqrt{44m}-15\sqrt{176m}=\) [ ].
