Question

$$MEANS$$

Evaluate

$S$

Differentiate w.r.t. S

$1$

Steps Using Definition of a Derivative

To find the mean of the set $S$ first add the members together.

$$S=S$$

The mean (average) of the set $S$ is found by dividing the sum of its members by the number of the members, in this case $1$.

$$\frac{S}{1}=S$$

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

$$S^{1-1}$$

Subtract $1$ from $1$.

$$S^{0}$$

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

$$1$$
