Решение:
- \( 16b^5 \cdot \frac{7c^2}{8b^{10}} = \frac{16b^5 \cdot 7c^2}{8b^{10}} = \frac{2 \cdot 7c^2}{b^5} = \frac{14c^2}{b^5} \)
- \( \frac{11n^4}{12p^6} \cdot 24p^8 = \frac{11n^4 \cdot 24p^8}{12p^6} = 11n^4 \cdot 2p^2 = 22n^4p^2 \)
- \( \frac{5a^5b^2}{28mn^2} \cdot \frac{8am^4}{15bn^3} \cdot \frac{21b^3n^6}{32a^6m^3} = \frac{5a^5b^2 \cdot 8am^4 \cdot 21b^3n^6}{28mn^2 \cdot 15bn^3 \cdot 32a^6m^3} = \frac{5 \cdot 8 \cdot 21 \cdot a^{5+1} \cdot b^{2+3} \cdot m^4 \cdot n^6}{28 \cdot 15 \cdot 32 \cdot a^6 \cdot b^{1+1} \cdot m^{1+3} \cdot n^{2+3}} = \frac{840 a^6 b^5 m^4 n^6}{13440 a^6 b^2 m^4 n^5} = \frac{840}{13440} b^{5-2} n^{6-5} = \frac{1}{16} b^3 n \)
Ответ: 4) \(\frac{14c^2}{b^5}\); 5) \(22n^4p^2\); 6) \(\frac{b^3n}{16}\).
