Solve k/3*3/1

$$\frac { k } { 3 } \cdot \frac { 3 } { 1 }$$

Evaluate

$$k$$

Solution Steps

Anything divided by one gives itself.

$$\frac{k}{3}\times 3$$

Cancel out 3 and 3.

$$k$$

Differentiate w.r.t. k

$$1$$

Steps Using Definition of a Derivative

Anything divided by one gives itself.

$$\frac{\mathrm{d}}{\mathrm{d}k}(\frac{k}{3}\times 3)$$

Cancel out 3 and 3.

$$\frac{\mathrm{d}}{\mathrm{d}k}(k)$$

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

$$k^{1-1}$$

Subtract 1 from 1.

$$k^{0}$$

For any term t except 0, t^{0}=1.

$$1$$
