tolong dong no8 cari f'(x) tentang turunan pake cara cepet gapapa, makasih ya...

jawab

turunan

(8).

f(x) = (3x² +4)⁵ (2x -1)⁴
y = uv --> y' = u' v + uv'

f'(x) = 5(6x)(3x² +4)⁴(2x-1)⁴ + 4(2)(2x- 1)³(3x²+4)⁵
f'(x)= 30x (3x²+ 4)⁴ (2x+1)⁴ + 8 (2x -1)³ (3x² + 4)⁵
f'(x) = (3x²+ 4)⁴ (2x-1)³  { 30x (2x+1) + 8(3x²+ 4)}
f'(x) = (3x² + 4)⁴ (2x -1)³ (60x² + 30x + 24x² + 32)
f'(x) = (3x² +4)⁴ (2x-1)³ ( 84x² + 30x +  32)
