Решение:

1. -3n²m⁶ ⋅ 17n⁵m⁷ = -3 ⋅ 17 ⋅ n² ⋅ n⁵ ⋅ m⁶ ⋅ m⁷ = -51n⁷m¹³
2. 0,6xy⁴z ⋅ 0,8x³y⁸z = 0,6 ⋅ 0,8 ⋅ x ⋅ x³ ⋅ y⁴ ⋅ y⁸ ⋅ z ⋅ z = 0,48x⁴y¹²z²
3. \[\frac{5}{9}a^7b^2c^6 \cdot \frac{27}{65}a^2b^3c = \frac{5 \cdot 27}{9 \cdot 65} a^7 \cdot a^2 \cdot b^2 \cdot b^3 \cdot c^6 \cdot c = \frac{5 \cdot 3}{1 \cdot 65} a^9b^5c^7 = \frac{15}{65} a^9b^5c^7 = \frac{3}{13} a^9b^5c^7\] = \(\frac{3}{13}a^9b^5c^7\)
4. -0,7d³ ⋅ (-0,2c⁶d) = -0,7 ⋅ (-0,2) ⋅ d³ ⋅ c⁶ ⋅ d = 0,14c⁶d⁴ = 0,14c⁶d⁴
5. p⁴q¹² ⋅ r³p = p⁴ ⋅ p ⋅ q¹² ⋅ r³ = p⁵q¹²r³
6. 0,3a⁶ ⋅ (2a²b)³ = 0,3a⁶ ⋅ 2³(a²)³b³ = 0,3 ⋅ 8 ⋅ a⁶ ⋅ a⁶ ⋅ b³ = 2,4a¹²b³ = 2,4a¹²b³
7. \[\frac{26}{45}m^3 \cdot (3mn^5)^2 = \frac{26}{45}m^3 \cdot 3^2m^2n^{10} = \frac{26}{45} \cdot 9 \cdot m^3 \cdot m^2 \cdot n^{10} = \frac{26 \cdot 9}{45} m^5n^{10} = \frac{26}{5} m^5n^{10} = 5.2m^5n^{10}\] = 5.2m⁵n¹⁰
8. (-x⁶y)³ ⋅ 11x⁴y⁵ = (-1)³(x⁶)³y³ ⋅ 11x⁴y⁵ = -1 ⋅ x¹⁸ ⋅ y³ ⋅ 11 ⋅ x⁴ ⋅ y⁵ = -11x²²y⁸ = -11x²²y⁸
