derivative of \sqrt[3]{x^3-1}

Solution

Solution

\frac{x ^{2}}{( x ^{3} - 1 ) ^{\frac{2}{3}}}

Solution steps

Apply the chain rule:

\frac{1}{3 ( x ^{3} - 1 ) ^{\frac{2}{3}}} \frac{d}{d x} (x^{3} - 1)

= \frac{1}{3 ( x ^{3} - 1 ) ^{\frac{2}{3}}} \frac{d}{d x} (x^{3} - 1)

\frac{d}{d x} (x^{3} - 1) = 3 x^{2}

= \frac{1}{3 ( x ^{3} - 1 ) ^{\frac{2}{3}}} \cdot 3 x^{2}

Simplify

\frac{1}{3 ( x ^{3} - 1 ) ^{\frac{2}{3}}} \cdot 3 x^{2} : \frac{x ^{2}}{( x ^{3} - 1 ) ^{\frac{2}{3}}}

= \frac{x ^{2}}{( x ^{3} - 1 ) ^{\frac{2}{3}}}
