mohon bantuannya.thnks

1. (a²b⁻³)⁴/(a²b⁶)⁻¹ = (a²)⁴(b⁻³)⁴/(a²)⁻¹(b⁶)⁻¹ = a²ˣ⁴b⁽⁻³⁾ˣ⁴/a²ˣ⁽⁻¹⁾b⁶ˣ⁽⁻¹⁾ = a⁸b⁻¹²/a⁻²b⁻⁶
                                = a⁸⁻⁽⁻²⁾b⁽⁻¹²⁾⁻⁽⁻⁶⁾ = a⁸⁺²b⁽⁻¹²⁾⁺⁶ = a¹⁰b⁻⁶ atau a¹⁰/b⁶

2. (x³)/(x²y²z) = x³⁻².1/y².1/z = x¹y⁻²z⁻¹ = xy⁻²z⁻¹ atau x/y²z

3. ⁴√(81x¹⁶y⁸) = (81 pangkat 1/4) (x pangkat 16/4) (y pangkat 8/4)
                        = (3⁴ pangkat 1/4) (x pangkat 4) (y pangkat 2)
                        = (3 pangkat 4/4) (x⁴) (y²) = 3¹x⁴y² = 3x⁴y²
