Ответ:
- а) \(\sqrt{\frac{1}{16}\cdot\frac{9}{25}}=\frac{1}{4}\cdot\frac{3}{5}=\frac{3}{20}\).
- б) \(\sqrt{\frac{64}{9}\cdot\frac{4}{49}}=\frac{8}{3}\cdot\frac{2}{7}=\frac{16}{21}\).
- в) \(\sqrt{\frac{0{,}25\cdot49}{9}}=\frac{0{,}5\cdot7}{3}=\frac{7}{6}\).
- г) \(\sqrt{\frac{169\cdot81}{100}}=\frac{13\cdot9}{10}=\frac{117}{10}\).
