14³
= 14 × 14 × 14
= 196 × 14
= 2.744
15⁴
= (15 × 15) × 15 × 15
= (225 × 15) × 15
= 3.375 × 15
= 50.625
Penjelasan dengan langkah-langkah:
14³ = (10 + 4)³
= 10³ + 3×10²×4 + 3×10×4² + 4³
= 1.000 + 1.200 + 480 + 64
= 2.200 + 544
15⁴ = 15² × 15²
= (10² + 2×10×5 + 5²) × (10² + 2×10×5 + 5²)
= (100 + 100 + 25) × (100 + 100 + 25)
= 225²
= 200² + 2×200×25 + 25²
= 40.000 + 10.000 + 625
