Ответ:

  1. \(\frac{(2^4)^3\cdot6^7\cdot3^2}{18^4\cdot2^9}=\frac{2^{12}\cdot(2\cdot3)^7\cdot3^2}{(2\cdot3^2)^4\cdot2^9}=\frac{2^{19}\cdot3^9}{2^{13}\cdot3^8}=2^6\cdot3=192\).
  2. \(\frac{2\cdot(5^3)^3\cdot9^4\cdot4^2}{10^7\cdot3^6}=\frac{2\cdot5^9\cdot3^8\cdot2^4}{(2\cdot5)^7\cdot3^6}=2^{-2}\cdot5^2\cdot3^2=\frac{225}{4}\).

Ответ: 1) 192; 2) \(\frac{225}{4}\).
