Need assistance with anyone who is familiar with a TI-89

[coder1]

I notice when I am trying to do a LOG() function I have to hit the alpha key and type out "LOG" How do I do a base of that? I know by default it is base 10 but what if I wanted to do LOG base 3

Thanks for any help

what are you in algebra 1?

log(whatever) / log(3)

chumpan, is that how you come up with a base?

"log(whatever) / log(3)"

If I wanted to calculate log base 5. how would i do that?

log(x)/log(base you want)

its the law of logs. learn it.
(you could have googled this really easily)

use ln for natural log that way you don't have to type it in like for base 10
ln(x)/ln( 10 )
