Solve 2d-2d+8d=

$$2 d - 2 d + 8 d =$$

Differentiate w.r.t. d

$$8$$

Steps Using Definition of a Derivative

Combine 2d and -2d to get 0.

$$\frac{\mathrm{d}}{\mathrm{d}d}(8d)$$

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

$$8d^{1-1}$$

Subtract 1 from 1.

$$8d^{0}$$

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

$$8\times 1$$

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

$$8$$

Evaluate

$$8d$$

Solution Steps

Combine 2d and -2d to get 0.

$$8d$$
