Differentiate w.r.t. x

$17$

Steps Using Definition of a Derivative

Combine $7x$ and $8x$ to get $15x$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(15x+2x)$$

Combine $15x$ and $2x$ to get $17x$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(17x)$$

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

$$17x^{1-1}$$

Subtract $1$ from $1$.

$$17x^{0}$$

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

$$17\times 1$$

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

$$17$$
