Performing Logarithmic Functions on a TI84 plus...
Does anybody have any insight on how to perform log functions on a TI graphing calculator? Because I clearly do not know how to. I know that
log4 times 8 is supposed to give me 3/2 but when I did it on my TI84 plus it gave me 4.8 something, so, anybody??? Help???

Ok, in what base is it ?

And is it $\log(4*8)$ or $8 \log(4)$
