Answer 1

5a. A : B = 3 : 5  | ×2
      B : C = 2 : 3  | ×5
-------------------------------
A : B : C = 6 : 10 : 15

Banyak kendaraan di SPBU C
= 15/6 × 126
= 315

5b. A : L = 4 : 3  | ×2
      L : E = 2 : 5  | ×3
--------------------------------
A : L : E = 8 : 6 : 15

Uang Lindy
= 6/(8 + 6 + 15) × 145.000
= 6/29 × 145.000
= 30.000

6b. (2⁴ × 8⁻²)/4⁻⁴
= (2⁴ × (2³)⁻²)/(2²)⁻⁴
= (2⁴ × 2⁻⁶)/2⁻⁸
= 2⁴⁺⁽⁻⁶⁾⁻⁽⁻⁸⁾
= 2⁴⁻⁶⁺⁸
= 2⁶
