30³ - 20² × 12²
(30 × 30 × 30) - (20 × 20) × (12 × 12)
(900 × 30) - 400 × 144
27000 - 400 × 144
27000 - 57.600
-30.600
Diket :
30³ = 30 × 30 × 30
20² = 20 × 20
12² = 12 × 12
Jawab :
= 30³ - 20² × 12²
= (30 × 30 × 30) - (20 × 20) × (12 × 12)
= (900 × 30) - 400 × 144
= (27.000 - (400 × 144)
= (27.000 - 57.600)
= (-30.600)
