and \[\log_{b}(b) = 1 \]
DanJS
  • DanJS
1) you can move the t down in front, left with log base 3 of 3 = 1 so it is true
DarkBlueChocobo
  • DarkBlueChocobo
what about number 2 is switching the 4.3 around make it the same?
DanJS
  • DanJS
yes, you can move the power to the front, but ln is base e, so you cant simplify that more... 2) is true too
DarkBlueChocobo
  • DarkBlueChocobo
For 3 Is it not true because they are being multiplied together not added seperately?
DanJS
  • DanJS
log(x*y) = log(x) + log(y)
DanJS
  • DanJS
do that , then move the power on y down
DarkBlueChocobo
  • DarkBlueChocobo
what do you mean when you say move the y down?
DanJS
  • DanJS
no, the power n, move that down in front like before

log(a^b) = b*log(a)
DarkBlueChocobo
  • DarkBlueChocobo
oh move it to the front?
DanJS
  • DanJS
yeah , just write down those 3 rules here to memorize http://www.purplemath.com/modules/logrules.htm
DarkBlueChocobo

Im going to say 3 is true also then saying it follows the rules
DarkBlueChocobo
  • DarkBlueChocobo

DanJS
  • DanJS
yes
DarkBlueChocobo
  • DarkBlueChocobo
I will memorize these again. I'm studying for my College algebra CLEP test
DanJS
  • DanJS
ah ok, yeah those types probs you just have to know a couple properties to manipulate the things
DanJS
  • DanJS
unless you can use a calculator, then just put in sample values and test to see if it is =
DarkBlueChocobo
  • DarkBlueChocobo
I can use a scientific calculator
DanJS
  • DanJS
oh, even if you didnt know the properties , you could pick any value for the variables, and test if both sides are the same
DanJS
  • DanJS
but that takes longer
