y = axⁿ --> y' = an xⁿ⁻¹
y = u/v --> y' = (u'v -uv') v²
y = u v --> y' = u'v + uv'
Penjelasan dengan langkah-langkah:
[tex]\sf 10. \ f(x) = -\frac{2}{5}x^{-\frac{3}{5}} + \frac{25}{x^{-7}}[/tex]
[tex]\sf f(x) = -\frac{2}{5}x^{-\frac{3}{5}} +{25}{x^{7}}[/tex]
[tex]\sf f'(x) = \frac{6}{25}x^{-\frac{8}{5}} + 175 x^6[/tex]
[tex]\sf \ 11. \ f(x) = (2x^3+7x)(x^2 +2x+5)[/tex]
u = 2x³ +7x dan v = x² + 2x + 5
f'(x) = u'v + uv'
f'(x) = (6x²+7)(x²+2x+ 5) + (2x³ +7x)(2x+2)
f'(x) = 10x⁴ +16x³ + 51 x² + 28 x + 35
12. f(x) = (5x² +7)(x - 2)
u = 5x² + 7 dan v = x - 2
f'(x) = u'v + uv'
f'(x) = (10x)(x -2) + (5x² +7)(1)
f'(x) = 15x² -20x + 7
