## Homework Statement

y = cos^3(5x^2-6)

## Homework Equations

## The Attempt at a Solution

I used the chain rule for this question but I am not sure about the cos^3 part. Using the chain rule i got

-10xSin^3(5x^2-6)

But was I supposed to use the power rule on the cos^3 part? I can think of 3 ways this could be done but I am not sure which way to go about it.

Thanks!
