Ответ:
- \(\sqrt{50}=\sqrt{25\cdot2}=5\sqrt2\).
- \(\sqrt{48}=\sqrt{16\cdot3}=4\sqrt3\).
- \(\sqrt{288}=\sqrt{144\cdot2}=12\sqrt2\).
- \(\sqrt{147x^4}=\sqrt{49\cdot3\cdot x^4}=7x^2\sqrt3\).
- \(\sqrt{175}=\sqrt{25\cdot7}=5\sqrt7\).
- \(\sqrt{\frac{108}{144}}=\sqrt{\frac34}=\frac{\sqrt3}{2}\).
- \(\sqrt{128}=\sqrt{64\cdot2}=8\sqrt2\).
- \(\sqrt{500}=\sqrt{100\cdot5}=10\sqrt5\).
- \(\sqrt{243}=\sqrt{81\cdot3}=9\sqrt3\).
- \(\sqrt{7.22}=\sqrt{\frac{722}{100}}=\frac{\sqrt{722}}{10}=\frac{\sqrt{361\cdot2}}{10}=\frac{19\sqrt2}{10}\).
- \(\sqrt{180}=\sqrt{36\cdot5}=6\sqrt5\).
- \(\sqrt{\frac{36}{50}}=\sqrt{\frac{18}{25}}=\frac{3\sqrt2}{5}\).
