Ответ:
- \( -2{,}4\sqrt{75}=-2{,}4\sqrt{25\cdot3}=-2{,}4\cdot5\sqrt3=-12\sqrt3.\)
- \( -100\sqrt{0{,}08}=-100\sqrt{0{,}04\cdot2}=-100\cdot0{,}2\sqrt2=-20\sqrt2.\)
- \(\frac23\sqrt{6\frac38}=\frac23\sqrt{\frac{51}{8}}=\frac23\cdot\frac{3\sqrt{34}}4=\frac{\sqrt{34}}2.\)
Ответ: 1) \(-12\sqrt3\); 2) \(-20\sqrt2\); 3) \(\frac{\sqrt{34}}2\).
