Question

$$-34b+(-29b)+42b$$

Evaluate

$-21b$

Differentiate w.r.t. b

$-21$

Steps Using Definition of a Derivative

Combine $-34b$ and $-29b$ to get $-63b$.

$$\frac{\mathrm{d}}{\mathrm{d}b}(-63b+42b)$$

Combine $-63b$ and $42b$ to get $-21b$.

$$\frac{\mathrm{d}}{\mathrm{d}b}(-21b)$$

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

$$-21b^{1-1}$$

Subtract $1$ from $1$.

$$-21b^{0}$$

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

$$-21$$
