Evaluate

$5y$

Show Solution

Differentiate w.r.t. y

$5$

Steps Using Definition of a Derivative

Combine $3y$ and $-5y$ to get $-2y$.

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

Combine $-2y$ and $7y$ to get $5y$.

$$\frac{\mathrm{d}}{\mathrm{d}y}(5y)$$

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

$$5y^{1-1}$$

Subtract $1$ from $1$.

$$5y^{0}$$

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

$$5\times 1$$

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

$$5$$
