Ответ:
- \(\frac{25^3\cdot14^2}{49\cdot10^6}=\frac{5^6\cdot(2\cdot7)^2}{7^2\cdot(2\cdot5)^6}=\frac{4}{25}\).
- \(\frac{12^2\cdot35^3}{28^2\cdot15^4}=\frac{(4\cdot3)^2\cdot(5\cdot7)^3}{(4\cdot7)^2\cdot(3\cdot5)^4}=\frac{7}{15}\).
- \(\frac{36^3\cdot15^2}{18^4\cdot10^3}=\frac{(2\cdot18)^3\cdot(3\cdot5)^2}{18^4\cdot(2\cdot5)^3}=\frac{9}{20}\).
- \(\frac{22^4\cdot3^3}{6^2\cdot121^2}=\frac{(2\cdot11)^4\cdot3^3}{(2\cdot3)^2\cdot(11^2)^2}=12\).
Ответ: а) \(\frac{4}{25}\); б) \(\frac{7}{15}\); в) \(\frac{9}{20}\); г) \(12\).
