Ответ:

  1. \(2^4\cdot3\cdot(2\cdot3)^7\cdot3^2:(2\cdot3^2)^4:2^9=2^2\cdot3^6:2^9=\frac{3^6}{2^7}=\frac{729}{128}\).

  2. \(2\cdot5^3\cdot(3^2)^4\cdot(2^2)^2:(2\cdot5)^7:3^6=2^5\cdot3^8\cdot5^3:2^7\cdot3^6\cdot5^7=\frac{9}{20^4}=\frac9{160000}\).

  3. \(3^9\cdot5^7\cdot2^2:(3^4)^2:(2\cdot5)^5=3\cdot2^{-3}\cdot5^2=\frac{75}{8}\).

  4. \((2\cdot3)^9\cdot3^4\cdot5^4:(2^3\cdot5^3):(2\cdot3^2)^7=2^{-1}\cdot3^{-1}\cdot5=\frac56\).

Ответ: 1) \(\frac{729}{128}\); 2) \(\frac9{160000}\); 3) \(\frac{75}{8}\); 4) \(\frac56\).
