2041^2n=243^n+2
what is the question :)
uhhh, find n?? :P
yes
i'm gonna use log to solve this, is that ok?? it's the weirdest method, i know :P
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??
yes
so after putting log on both sides, and then you bring down the indices on both sides, and you get \[2n \log_{}2041 = n+2\log_{}243\]
Take 2log2041 common
take out the value of log 2041
This question is only possible by using logs
\[ 2 n \log (2014)=(n+2) \log (243) \\ 2 n \log (2014)-n \log (243)=2 \log (243)\\ n (2 \log (2014)-\log (243))=2 \log (243)\\ n=\frac{2 \log (243)}{2 \log (2014)-\log (243)}=1.12995 \]
then you do \[\frac{\log_{}2041}{\log_{}243} = \frac{n+2}{2n}\]
then 2.775n = n+2, and then you get n as what i got above :P
@tanvidais13 did you see how I did it?
ok thnks
yupss, i did, it's just i'd typed the whole thing out before, and then forgot to post it :P and then posted in 10 years later. and your method seems fin too :D
*fine.
