10. (b^-2)^3 : b^-1
11. (1/y-1)^2 x (y^-3)^4
12. p^-3 x q^2 x 5^-4
13. 3x^2y^-3
14. p^-1 q r^-1
15. 1/4 x^2 y^-3 2^-1

Answer 1

1. caranya dibalik mas, jadinya per, = 1/3^4
2. 3 x 5^-2 = 3/5^2
3. a^-3 = 1/a^3
4. 4/b^-6 = 4 x b^6
5. 1/2 a^-2 = 1/2 / a^2
6. 1/5 b^-4 = 1/5 / b^4
7. jika dikali pertama hasilnya 2^-1 = 1/2
8. 3^-4 / 3^2 = 3^-6= 1/3^6
9. hasil kali 1 = a^5/a^12 = a^-7 = 1/a^7
10. b^-6/b^-1 = b^-5 = 1/b^5
11. hasil kali 1 = 1/y^2-1 x y^-12, = 1/y^14-1
12. 1/p^3 x q^2 x 1/5^4
13. 3x^2 x 1/y^3
14. 1/px q x 1/r
15. 1/4 x^2 1/y^3 x 1/2

Answer 2

1. 3^⁻4 = 1/3^4 = 1/81
2. 3 x 5^-2 = 3/5^2 = 3/25
3. a^-3 = 1/a^3
4. 4b^6
5. 1/2 a^-2 = (1/2)a^2
6. (1/5)b⁴
7. 2^-3+2 = 2^-1 = 1/2
8. 3^-4-2 = 3^-6 = 1/3^6
9. a^3+2-12 = a^-7 = 1/a^7
10. b^-6⁻(⁻¹) = b^-5 = 1/b^5
11.y⁻¹²⁻(⁻²) = y⁻¹⁰ = 1/y¹⁰
12. q²/p³ 5⁴
13. 3x²y⁻³ = 3x²/y³
14. p⁻¹ q r⁻¹ = q/pr
15.(1/4)x²/2y³ = (1/8)x²/y³
