Tentukan turunan pertama dari: f(x)= 5x^3√x - 7x√x - x^1/3 Tolong dibantu..

[tex]f(x) = 5x \sqrt[3]{x} - 7x \sqrt{x} - {x}^{ \frac{1}{3} } = 5 {x}^{ \frac{4}{3} } - 7 {x}^{ \frac{3}{2} } - {x}^{ \frac{1}{3 }} \\ {f}^{1} (x) = \frac{20}{3} {x}^{ \frac{1}{3} } - \frac{21}{2} {x}^{ \frac{1}{2} } - \frac{1}{3} {x}^{ - \frac{2}{3} } = \frac{20}{3} \sqrt[3]{x} - \frac{21}{2} \sqrt{x} - \frac{1}{3x \sqrt{x} } [/tex]
