(I guess this is what you are looking for; didn't need A or C).
Step-by-step explanation:
It seems like to wants us to to find in terms of .
First thing I'm going to do is rewrite using the quotient rule.
The quotient rule says:
So that means for our expression we have:
Second thing I'm going to do is say that .
Now I know 16 is 4 squared so the third thing I'm going to do is replace 16 with 4^2 with aim to use power rule.
The fourth thing I'm going to is apply the power rule. The power rule say . So I'm applying that now:
So we are given that is . So this is the last thing I'm going to do is apply that substitution:
