Steps Using Definition of a Derivative

Multiply 2 and 2 to get 4.

$$\frac{\mathrm{d}}{\mathrm{d}b}(4b)$$

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

$$4b^{1-1}$$

Subtract 1 from 1.

$$4b^{0}$$

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

$$4\times 1$$

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

$$4$$

Evaluate

$$4b$$

Solution Steps
