Ответ:
- \(\dfrac{(6^4)^4}{(6^5)^3}=6^{16-15}=6\).
- \(\dfrac{8^3}{4^4}=\dfrac{2^9}{2^8}=2\).
- \(\dfrac{7^{14}\cdot(7^2)^3}{(7^3)^6\cdot7^2}=7^{14+6-18-2}=1\).
- \(\dfrac{25^3\cdot125^9}{5^{10}}=5^{6+27-10}=5^{23}\).
- \(\dfrac{3^8\cdot7^8}{21^7}=\dfrac{21^8}{21^7}=21\).
- \(\dfrac{5^9\cdot4^6}{20^6}=\dfrac{5^9\cdot2^{12}}{(2^2\cdot5)^6}=5^3=125\).
Ответ: 1) 6; 2) 2; 3) 1; 4) \(5^{23}\); 5) 21; 6) 125.
