Answer 1

Jawab:
[1.]  = a³b
[2.] = a⁵/b⁷
[3.] = a⁴/b⁶
[4.] = b⁵

Penjelasan:
[1.]  (ab²a⁶) ÷ (a⁴b) = a·a⁶a⁻⁴b²b⁻¹
= a¹⁺⁶⁻⁴b²⁻¹ = a⁷⁻⁴b¹ = a³b

[2.] (a⁴÷b²a²) ÷ (ab⁵) = (a⁴a²) ÷ (ab²b⁵)
= a⁴a²a⁻¹b⁻²⁻⁵ = a⁴⁺²⁻¹b⁻⁷ = a⁶⁻¹b⁻⁷
= a⁵b⁻⁷ = a⁵/b⁷

[3.] (a⁴a³÷b²) ÷ (a³b⁴) = (a⁴a³) ÷ (a³b⁴b²)
= a⁴ ÷ (b⁴b²) = a⁴/(b⁴⁺²) = a⁴/b⁶

[4.] (a²b³b²) ÷ (a⁴÷a²) = (a²b³b²) ÷ (a⁴a⁻²)
= a²⁻⁴⁻⁽⁻²⁾b³⁺² = a²⁻⁴⁺²b⁵ = a⁴⁻⁴b⁵ = a⁰b⁵
= b⁵
