so I believe the first one would be correct cause when put into 3^t=3^t

Other answers:

and \[\log_{b}(b) = 1 \]
1) you can move the t down in front, left with log base 3 of 3 = 1 so it is true
what about number 2 is switching the 4.3 around make it the same?
yes, you can move the power to the front, but ln is base e, so you cant simplify that more... 2) is true too
For 3 Is it not true because they are being multiplied together not added seperately?
log(x*y) = log(x) + log(y)
do that , then move the power on y down
what do you mean when you say move the y down?
no, the power n, move that down in front like before
|dw:1438918830800:dw|
log(a^b) = b*log(a)
oh move it to the front?
yeah , just write down those 3 rules here to memorize http://www.purplemath.com/modules/logrules.htm
Im going to say 3 is true also then saying it follows the rules
would that be correct
yes
I will memorize these again. I'm studying for my College algebra CLEP test
ah ok, yeah those types probs you just have to know a couple properties to manipulate the things
unless you can use a calculator, then just put in sample values and test to see if it is =
I can use a scientific calculator
oh, even if you didnt know the properties , you could pick any value for the variables, and test if both sides are the same
but that takes longer

Thank you :)
