Ответ:
- \(3^{16} : (3^5)^3 = 3^{16} : 3^{15} = 3^1 = 3\).
- \((5^7)^3 : (5^4)^5 = 5^{21} : 5^{20} = 5^1 = 5\).
- \(6^8 \cdot (6^5)^4 : 6^{25} = 6^{8+20-25} = 6^3 = 216\).
- \(49^2 : 7^3 = (7^2)^2 : 7^3 = 7^4 : 7^3 = 7^1 = 7\).
- \(\dfrac{8^{14} \cdot (8^4)^6}{(8^5)^7 \cdot 8} = 8^{14+24-35-1} = 8^2 = 64\).
- \(\dfrac{9^5 \cdot 81^6}{3^{30}} = \dfrac{3^{10} \cdot 3^{24}}{3^{30}} = 3^4 = 81\).
Ответ: 1) 3; 2) 5; 3) 216; 4) 7; 5) 64; 6) 81.
