[don1231915]

Differentiating an equation!

Homework Statement

How do I differentiate this

V(x) = 300x * sqrt(1296-x^2)

The Attempt at a Solution

I tried using the product rule but that didnt work at all


PLease help

Thank you so much!

Hint $$f(x)=\sqrt{g(x)}$$
Then:
$$f'(x)=\frac{g'(x)}{2\sqrt{g(x)}}<br /> [$$
Now use the product rule

To elaborate on what hunt_mat said, you do have to use the product rule, but you also need to use the chain rule.
