Question

$$21z-4z-1$$

Differentiate w.r.t. z

$17$

Steps Using Derivative Rule for Sum

Combine $21z$ and $-4z$ to get $17z$.

$$\frac{\mathrm{d}}{\mathrm{d}z}(17z-1)$$

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 $nax^{n-1}$.

$$17z^{1-1}$$

Subtract $1$ from $1$.

$$17z^{0}$$

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

$$17\times 1$$

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

$$17$$

Evaluate

$17z-1$
