(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The problem is to differentiate the function.

y=cos^{4}(x^{2}+ e^{x})

2. Relevant equations

cos(x)'= -sin(x), (x^{n})'=n*x^{n-1}, (e^{x})'=e^{x}*x'

3. The attempt at a solution

Thought it would be the chain rule. Here's what I came up with:

y'=4cos^{3}(-sin(x^{2}+ e^{x})(2x + e^{x})

Is this right? If not, any suggestions on what I did wrong?
