what is the question :)
OpenStudy (anonymous):
uhhh, find n?? :P
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
i'm gonna use log to solve this, is that ok?? it's the weirdest method, i know :P
OpenStudy (anonymous):
Log would be helpfil

i have NO clue of what i've done, (lol) btu the answer i've got is 1.127. Should i show the working??
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
so after putting log on both sides, and then you bring down the indices on both sides, and you get
\[2n \log_{}2041 = n+2\log_{}243\]
OpenStudy (anonymous):
Take 2log2041 common
OpenStudy (anonymous):
take out the value of log 2041

This question is only possible by using logs
OpenStudy (anonymous):
\[
2 n \log (2014)=(n+2) \log (243) \\
2 n \log (2014)-n \log (243)=2
\log (243)\\
n (2 \log (2014)-\log (243))=2
\log (243)\\
n=\frac{2 \log (243)}{2 \log
(2014)-\log (243)}=1.12995
\]
OpenStudy (anonymous):
then you do
\[\frac{\log_{}2041}{\log_{}243} = \frac{n+2}{2n}\]
OpenStudy (anonymous):
then 2.775n = n+2, and then you get n as what i got above :P

@tanvidais13 did you see how I did it?
