Question

$$(3a+7)+(6a-2)$$

Evaluate

$9a+5$

Differentiate w.r.t. a

$9$

Steps Using Derivative Rule for Sum

Combine $3a$ and $6a$ to get $9a$.

$$\frac{\mathrm{d}}{\mathrm{d}a}(9a+7-2)$$

Subtract $2$ from $7$ to get $5$.

$$\frac{\mathrm{d}}{\mathrm{d}a}(9a+5)$$

The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is $0$. The derivative of $ax^{n}$ is $nax^{n-1}$.

$$9a^{1-1}$$

Subtract $1$ from $1$.

$$9a^{0}$$

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

$$9\times 1$$

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

$$9$$
