Solve 4xdiv2x^2=

$$4x \div 2 { x }^{ 2 } =$$

Evaluate

$$2x^{3}$$

Solution Steps

Divide 4x by 2 to get 2x.

$$2xx^{2}$$

To multiply powers of the same base, add their exponents. Add 1 and 2 to get 3.

$$2x^{3}$$

Differentiate w.r.t. x

$$6x^{2}$$

Steps Using Definition of a Derivative

Divide 4x by 2 to get 2x.

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

To multiply powers of the same base, add their exponents. Add 1 and 2 to get 3.

$$\frac{\mathrm{d}}{\mathrm{d}x}(2x^{3})$$

The derivative of ax^{n} is nax^{n-1}.

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

Multiply 3 times 2.

$$6x^{3-1}$$

Subtract 1 from 3.

$$6x^{2}$$
