tolong bantu pakai caranya, dikumpulin besok
Rumus Turunan :
[tex]\frac{d}{dx}\,ax^n=an\,x^{n-1}[/tex]
3)
[tex]f(x)=5\sqrt[3]{x^2}\\\\f(x)=5\,x^{\frac{2}{3}}[/tex]
Turunan pertama
[tex]f'(x)=\frac{d}{dx}\,f(x)\\\\f'(x)=\frac{d}{dx}\,5x^{\frac{2}{3}}\\\\f'(x)=\frac{10}{3}\,x^{-\frac{1}{3}}\\\\f'(x)=\frac{10}{3x^{\frac{1}{3}}}\\\\f'(x)=\frac{10}{3\sqrt[3]{x}}[/tex]
4)
[tex]f(x)=(2x+3)(x^3-2x^2)\\\\f(x)=2x^4-x^3-6x^2[/tex]
Turunan pertama
[tex]f'(x)=\frac{d}{dx}\,f(x)\\\\f'(x)=\frac{d}{dx}\,2x^4-x^3-6x^2\\\\f'(x)=8x^3-3x^2-12x\\[/tex]
