\[\log_{a} b=c\]
angela210793
  • angela210793
so a^c=b look wikipedia http://en.wikipedia.org/wiki/Logarithm

that it ried to do this on 2^2=4 but failed ...
angela210793
  • angela210793
ok w8
anonymous
  • anonymous
aha then log2,4=2??
angela210793
  • angela210793
\[\log_{2} 2=1\]
angela210793
  • angela210793
yes cause 2^2=4
anonymous
  • anonymous
ok then what can we use this for??
angela210793
  • angela210793
hmmmmm....to confuse students with some more formulas i guess :P:P:P:P
anonymous
  • anonymous
then 4^4=16 so \[\log_{16\[\log_{4}16 \]} \]=4??
anonymous
  • anonymous
rofl i failed at typing equestion :P
anonymous
  • anonymous
lgot4,16=4??
angela210793
  • angela210793
nooo 4^2=16
anonymous
  • anonymous
ahh then wait
angela210793
  • angela210793
so log with base 4 of 16=2
anonymous
  • anonymous
log2,16=??
anonymous
  • anonymous
log2,16=4
anonymous
  • anonymous
hmm :(
angela210793
  • angela210793
\[\log_{4}16=2 \]
angela210793
  • angela210793
listen \[\log_{a}b=c \]
angela210793
  • angela210793
so a^c=b
anonymous
  • anonymous
so iw we do it 8 = 2^3 its log2,8=4!!!!
anonymous
  • anonymous
log2,8=3
anonymous
  • anonymous
not 4
angela210793
  • angela210793
Korcan log2,8=3 cause 2^3=8
anonymous
  • anonymous
ok just have to solve 10 questions and it will be better
angela210793
  • angela210793
so a is the base and c is the exponent so b can be b=a^c
anonymous
  • anonymous
okay
angela210793

did u read the article from wikipedia i sent u?

huh? u read it so fast?...C'mon Korcan don't b lazy...read it carefully :P:P:P

100 ^2 = 10000 so log2,100=1000 YEA?
anonymous
  • anonymous
i can read over 5 pages in 47 secs (i counted it :D )
angela210793
  • angela210793
Nope....log100,10000=2
angela210793
  • angela210793
i can bet u have seen the pics only :P:P:P
anonymous
  • anonymous
rofl wait i did wrong typing xd
angela210793
  • angela210793
cause 100^2=10000
anonymous
  • anonymous
if u get confused it is sometimes easier to consider logs to the base 10 you know that 10^2 = 100 remember the 10 is the base , 2 is the log and 100 is the result so 'log to the base 10 of 100 is 2' : log_{10} 100 = 2 when considering other bases refer to the above two facts
angela210793
  • angela210793
right....i told u to read tht carefully :P
anonymous
  • anonymous
i solved it ture to my notebook xd ( i always do this when i am too exiting)
angela210793

hahahha lool
angela210793
  • angela210793
Jimmy is right but the right formula is the 1 i told you..and u have included all in that 1
anonymous
  • anonymous
ok 6^2=36 so log6,36=2 solved true?
angela210793
  • angela210793
Yuppiiiii!!!! Yes u did :):)
anonymous
  • anonymous
FINALLY :D xd now what i have to learn ? :P
anonymous

err angela can ou be on at fb right now?
angela210793

\[\log_{a}b+\log_{a} c=\log_{a} c*d\]
angela210793
  • angela210793
No i can't Korcan..I'm sorry..I told you i'll log in again after tomorrow :):)
angela210793
  • angela210793
\[\log_{a}b-\log_{a}c=\log_{a}b/c \]
anonymous
  • anonymous
yea remember but 2^1=2 and log2,2 = 1 then i think that u ll be on after 1 day xp xp :P
angela210793
  • angela210793
\[\log_{a} b^n=n \log_{a} b\]
angela210793
