1. 27 p^-8 / 9 p^2

2. 81 k^4 b^-3 / 3^3 k^-8 b^5

3. (2a^4)^2 / b^7 : (a^2)^-3 / 2b

Answer 1

1. 3³ p^-8 / 3² p²
= 3³-² p^-8-2
=3 p^-10
=3 / p^10

2. 3⁴ k⁴ b-³ / 3³ k^-8 b^5
=3⁴-³ k^4-(-8) b-³-5
=3 k^12 b^-8
=3 k^12 / b^8

3. 2²a^8/b^7 : a^-6/2b
=2²a^8/ b^7 × 2b/a^-6
=2²+¹ a^8-(-6) b^1-7
=2³ a^14 b^-6
=2³ a^14 / b^6
