Apply the quotient rule, which is:
and .
To find :
Apply the power rule: goes to
To find :
Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
The derivative of is .
The result of the chain rule is:
Now plug in to the quotient rule:
Now simplify:
The answer is:
1 2 ------- - ------- 2 3 log (x) log (x)
/ 3 \ 2*|-1 + ------| \ log(x)/ --------------- 3 x*log (x)
/ 12 \ 2*|1 - -------| | 2 | \ log (x)/ --------------- 2 3 x *log (x)
