Ответ:
- \(\dfrac{5^9\cdot13^9}{65^8}=\dfrac{(5\cdot13)^9}{65^8}=\dfrac{65^9}{65^8}=65\).
- \(\dfrac{24^7}{8^6\cdot3^6}=\dfrac{24^7}{(8\cdot3)^6}=\dfrac{24^7}{24^6}=24\).
- \(\dfrac{4^{10}\cdot11^8}{44^8}=\dfrac{4^{10}\cdot11^8}{(4\cdot11)^8}=4^{10-8}=4^2=16\).
- \(\dfrac{15^{12}}{3^{12}\cdot5^{10}}=\dfrac{(3\cdot5)^{12}}{3^{12}\cdot5^{10}}=5^{12-10}=25\).
Ответ: 1) 65; 2) 24; 3) 16; 4) 25.
