Solve d/dx(x^2)^2

$$\frac { d } { d x } ( x ^ { 2 } ) ^ { 2 }$$

Evaluate

$$4x^{3}$$

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).

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

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}.

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

Simplify.

$$4x^{1}\left(x^{2}\right)^{1}$$

For any term t, t^{1}=t.

$$4xx^{2}$$

Differentiate w.r.t. x

$$12x^{2}$$
