hi quick question for this:(adsbygoogle = window.adsbygoogle || []).push({});

simplify the following

ln(4+4y+4y^2) i know i need to use those simplifying rules for ln which are ln(xy)=lnx+lny

ln(1/x)=-lnx

ln(x/y)=lnx-lny

ln(x^r)=rlnx

but for the question im asked to simplify.. it doesnt really follow any of these... I was wondering what the rule is for this type of question. Do i do:

ln4+ln4y+ln4y^2?? Thanks!
