Can someone please help me with the steps on this particular problem
I have no clue, especially with the nth root
Begin by dividing each of the three terms in the numerator (top) by the term in the denominator.
Before you do this, here are a few things you'll need to know about handling indices (powers):
First, then, divide by like this:
Now divide by , and then divide by in the same way.
You'll then have three separate terms in which you can differentiate in the usual way.
Hope that helps.
