Penjelasan dengan langkah-langkah:
1. f (x) = (3x + 3)(x³ + 5)
f' (x) = d/dx ( (3x + 3) × (x³ + 5) )
f' (x) = d/dx (3x⁴ + 15x + 3x³ + 15)
f' (x) = d/dx(3x⁴) + d/dx(15x) + d/dx(3x³) + d/dx(15)
f' (x) = 3 × 4x³ + d/dx(15x) + d/dx(3x³) + d/dx(15)
f' (x) = 3 × 4x³ + 15 + d/dx(3x³) + d/dx(15)
f' (x) = 3 × 4x³ + 15 + 3 × 3x² + d/dx(15)
f' (x) = 3 × 4x³ + 15 + 3 × 3x² + 0
f' (x) = 12x³ + 9x² + 15
