1] (x⁻⁵ / (x⁻² . y⁻¹))⁶ = (x⁻⁵⁺² . y¹)⁶
= x⁻³ˣ⁶ . y¹ˣ⁶
= x⁻¹⁸ y⁶
2] ((24 . a³ . b⁻²) / (6 . a⁻⁵ . b))⁻² = (4 . a³⁺⁵ . b⁻²⁻¹)⁻²
= 4⁻² . a⁸ ˣ ⁻² . b⁻³ ˣ ⁻²
= 4⁻² . a⁻¹⁶ b⁶
= b⁶ / (4² . a¹⁶)
= b⁶ / (16 . a¹⁶)
3] (m n³ / (2 n ⁻³))⁻² = (2⁻¹ . m . n³⁺³)⁻²
= 2⁻¹ ˣ ⁻² . m⁻² . n⁶ ˣ ⁻²
= 2² . m⁻² . n⁻¹²
= 4 / (m² . n¹²)
4] ab⁻² . ba⁻² . 1/(ab)⁻³ = a¹⁻² . b⁻²⁺¹ . a³b³
= a⁻¹⁺³ . b⁻¹⁺³
= a² b²
5] (5x⁻¹ y⁻⁴) / ((3y⁵)⁻² x⁹) = (5 x⁻¹ y⁻⁴) / (3⁻² y⁵ ˣ ⁻² . x⁹)
= 5 . 3² . x⁻¹⁻⁹ y⁻⁴⁺¹⁰
= 5 . 9 . x⁻¹⁰ y⁶
= (45 y⁶) / x¹⁰
