Steps Using Definition of a Derivative

Combine $8a$ and $-3a$ to get $5a$.

$$\frac{\mathrm{d}}{\mathrm{d}a}(5a+2a)$$

Combine $5a$ and $2a$ to get $7a$.

$$\frac{\mathrm{d}}{\mathrm{d}a}(7a)$$

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

$$7a^{1-1}$$

Subtract $1$ from $1$.

$$7a^{0}$$

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

$$7\times 1$$

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

$$7$$
