derivative of

(7 x^{3} + x^{2})^{\frac{2}{3}}

\frac{2 ( 21 x ^{2} + 2 x )}{3 ( 7 x ^{3} + x ^{2} ) ^{\frac{1}{3}}}

Solution steps

\frac{d}{d x} ((7 x^{3} + x^{2})^{\frac{2}{3}})

Apply the chain rule:

\frac{2}{3 ( 7 x ^{3} + x ^{2} ) ^{\frac{1}{3}}} \frac{d}{d x} (7 x^{3} + x^{2})

= \frac{2}{3 ( 7 x ^{3} + x ^{2} ) ^{\frac{1}{3}}} \frac{d}{d x} (7 x^{3} + x^{2})

\frac{d}{d x} (7 x^{3} + x^{2}) = 21 x^{2} + 2 x

= \frac{2}{3 ( 7 x ^{3} + x ^{2} ) ^{\frac{1}{3}}} (21 x^{2} + 2 x)

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{2 ( 21 x ^{2} + 2 x )}{3 ( 7 x ^{3} + x ^{2} ) ^{\frac{1}{3}}}

\frac{\partial}{\partial x} ((2 x + 7 y)^{11})

\int cos^{2} (\frac{nπ x}{L}) d x

\int (x + 6) d x

(x + 2)^{2} + (y - 3)^{2} = 37, (- 3, 9)
