I have the problem
Expand:
$\displaystyle 4\ln(x)+\left(\frac{\ln(x^2+3)}{2}\right)$
Is it legal to distribute ln like this?
Here is what I got:
$\displaystyle 4\ln(x)+\left(\frac{2\ln(x)+\ln(3)}{2}\right)$
Thanks.

Dear dwatkins,
$\displaystyle \ln{(a\times{b})}=\ln{(a)}+\ln{(b)}~but~\ln(a+b)\n eq{\ln{(a)}+\ln{(b)}}$
