going through practice problems for a test
Am I doing this correctly?
Find the differential:
via power rule:
and so,
thank you in advance
You need the power rule AND the chain rule...
Let = f(x) and
Then, (this is just the chain rule)
So in your case, you take the derivative of f correctly, but never multiply by the derivative of g
Also, that isn't inside the square root, so you can't multiply by under the radical
