5 log (x)
d / 5 \ --\log (x)/ dx
Let u=log(x)u = \log{\left(x \right)}u=log(x).
Apply the power rule: u5u^{5}u5 goes to 5u45 u^{4}5u4
Then, apply the chain rule. Multiply by ddxlog(x)\frac{d}{d x} \log{\left(x \right)}dxdlog(x):
The derivative of log(x)\log{\left(x \right)}log(x) is 1x\frac{1}{x}x1.
The result of the chain rule is:
The answer is:
4 5*log (x) --------- x
3 5*log (x)*(4 - log(x)) ---------------------- 2 x
2 / 2 \ 10*log (x)*\6 + log (x) - 6*log(x)/ ----------------------------------- 3 x
