Solve 1/3*{x^frac{2{3}}}

$$\frac{ 1 }{ 3 \times { x }^{ \frac{ 2 }{ 3 } } }$$

Differentiate w.r.t. x

$$-\frac{2}{9x^{\frac{5}{3}}}$$

Steps Using Chain Rule

If F is the composition of two differentiable functions f\left(u\right) and u=g\left(x\right), that is, if F\left(x\right)=f\left(g\left(x\right)\right), then the derivative of F is the derivative of f with respect to u times the derivative of g with respect to x, that is, \frac{\mathrm{d}}{\mathrm{d}x}(F)\left(x\right)=\frac{\mathrm{d}}{\mathrm{d}x}(f)\left(g\left(x\right)\right)\frac{\mathrm{d}}{\mathrm{d}x}(g)\left(x\right).

$$-\left(3x^{\frac{2}{3}}\right)^{-1-1}\frac{\mathrm{d}}{\mathrm{d}x}(3x^{\frac{2}{3}})$$

The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of ax^{n} is nax^{n-1}.

$$-\left(3x^{\frac{2}{3}}\right)^{-2}\times \frac{2}{3}\times 3x^{\frac{2}{3}-1}$$

Simplify.

$$-2x^{-\frac{1}{3}}\times \left(3x^{\frac{2}{3}}\right)^{-2}$$

Evaluate

$$\frac{1}{3x^{\frac{2}{3}}}$$
