(47/50)f(x) = x² + 3x × 5x²f(6) =
3.276
Penjelasan dengan langkah-langkah:
Diketahui:
- x = 6
Ditanya:
- f(x) = x² + 3x × 5x² = … ?
Jawab:
- f(x) = x² + 3x × 5x²
- f(6) = 6² + 3(6) × 5(6)²
- f(6) = 6² + 3(6) × 5(6.6)
- f(6) = 6² + 3(6) × 5(36)
- f(6) = 6² + 3(6) × 180
- f(6) = 6² + (3.6) × 180
- f(6) = 6² + 18 × 180
- f(6) = (6.6) + 18 × 180
- f(6) = 36 + 18 × 180
- f(6) = 36 + 3.240
- f(6) = 3.276
Kesimpulan:
Jadi, hasil dari f(x) = x² + 3x × 5x² adalah 3.276

f(x) = x² + 3x × 5x²
f(6) = 6² + 3(6) × 5(6²)
f(6) = (6 × 6) + 18 × 5 (6 × 6)
f(6) = 36 + 18 × 5(36)
f(6) = 36 + 18 × 180
f(6) = 36 + 3.240
f(6) = 3.276
