# Math Help - differentiate this equation...

1. ## differentiate this equation...

I blanked on how to solve this. I thought i take the seventh root and put it inside, so it would be (x)^7/2 then differentiate ...but i was wrong. Any takers? Thanks!

2. Wouldn't it just be (1/(seventh root of x)) * Chain rule?

3. $\sqrt[7]{x} = x^{1/7}$

You can use chain rule.

4. Or even easier:

$f(x) = \ln(\sqrt[7]{x}) = \ln(x^{1/7}) = \frac{1}{7} \ln(x)$

5. It was that part i forgot. thanks.
