# Math Help - Derivative With Natural Logs

1. ## Derivative With Natural Logs

$(1+\ln x)^7$

I would have to use the general power rule rather than log properites correct . so the answer should be.

$\frac{7}{x} (1 + \ln x)^6$

2. You must use the chain rule

$y=(1+\ln x)^7$

then

$y'=7(1+\ln x)^6 \cdot (1+\ln x)' =7(1+\ln x)^6 \cdot \displaystyle\frac{1}{x}$
