#### Answer:

#### Explanation:

This is a case of using the power rule and the chain rule.

First, we note that

Now we can apply the power rule, where we multiply the function by the exponent then decrease the exponent by one:

Then we apply the chain rule, which tells us to multiply this result by the derivative of the "inside" function. In our case, the "inside" function is

In radical form, this is
