Solve 2d+d

$$2 d + d$$

Differentiate w.r.t. d

$$3$$

Steps Using Definition of a Derivative

Combine 2d and d to get 3d.

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

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

$$3d^{1-1}$$

Subtract 1 from 1.

$$3d^{0}$$

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

$$3\times 1$$

For any term t, t\times 1=t and 1t=t.

$$3$$

Evaluate

$$3d$$

Solution Steps

Combine 2d and d to get 3d.

$$3d$$
