Solution

9. 2x² -3x = x (2x - 3)

10 8x³ - 5x² = x²(8x - 5)

11. 6v³ - v⁴ = v³ (6 - v)

12.(xy⁴)⁴ = x⁴y¹⁶

13. v / (2v⁰)⁴ = v / ( 2 )⁴ = v/ 16 ( as v⁰ = 1)

14.2x² / (x⁴)^-1 = 2x² / x^-4 = 2x² * x⁴ = 2x⁶

15. (v² . 4v⁴ ) ^-3 = (4v⁶)^-3 = 4^-3 v ^-18 = 1/ (64 v¹⁸)

16. x^-2 (3x³)^-1 = x^-2 (3^-1x^-3) = 3^-1 x^-5 = 1/ ( 3 x⁵ )

17. (4b³)³ . b² = (4)³ . b⁹ . b² = 64b¹¹

18. 4v^-4 . (3v⁴)⁴ = 4v^-4 . 3⁴ . v¹⁶ = 324 v¹²

^{19 (}3n^-3 .2n²) / (2n^-4)² = 6n ^-1 / (2² . n^-8) = (6/4) (n^-1/ n^-8) = 3/2 n⁷

20. (3x² . 3x^-4)³ / (4x²)³ = (9x^-2)³ / 4³. x⁶ = 9³ . x^-6 / 64 x⁶ = (729/64)x^-12
