= (-2)^{8 + 3} / (-2)⁹

= (-2)¹¹ / (-2)⁹

= (-2)^11-9 = (-2)³ = -2 x (-2) x (-2) = -8

4. 1/ 6(a + b)^-7 = 1/ 6(a + b)^-7  = 6(a + b)7

5. a⁵ x a⁶ = a^{5 + 6} = a¹¹ = 1 / a^-11

6. x¹y² / 2z⁶ = 1/x^-1y^-2 X (1/2z⁶) = 1/x^-1 y ² x 2z^-6 = 2z^-6 / x^-1 y^-2

7. 5 (x² – y²) (x² – y²)0 = 5 (x² – y²) (1) = 5x² – 5y²

8. 6³ + 6²= (6 x 6 x 6) + (6 x 6) = 216 + 36 = 252

8⁴ / 8² = 8 ^{4 – 2} = 8² =64

9. 5⁵ / 25² dbuat terlebih dahulu agar bilangan pokoknya sama menjadi 5.
