Ответ:
- \(\sqrt{49\cdot2.25}=\sqrt{110.25}=10.5\).
- \(2\frac{23}{49}=\frac{121}{49}\), а \(6\frac{1}{4}=\frac{25}{4}\). Тогда \(\sqrt{\frac{121}{49}\cdot\frac{25}{4}}=\sqrt{\frac{3025}{196}}=\frac{55}{14}\).
- \(\sqrt{18\cdot14\cdot28}=\sqrt{7056}=84\).
- \(\sqrt{12.5\cdot0.5}=\sqrt{6.25}=2.5\).
- \(\frac{\sqrt{50}}{\sqrt{1250}}=\sqrt{\frac{50}{1250}}=\sqrt{\frac{1}{25}}=\frac{1}{5}\).
