Thread: "Sub" Logarithmic Equations

I have a TI-83 Plus and I don't know how to make, say: "log 1/3" where the "1/3" is sub to the "log".

Any help?

First off you have to take the log of something, ex.:

As for inputing different logarithmic bases into your calculator, here's a useful property:
where c can be any number.

So for your calculator, you'll either be considering c = 10 (denoted just log on the calculator) or c = e (where )

Example:
(base 10 is implied).

...so what buttons do I push to put in the sub?

Don't know if you saw my edited post but I posted an example.

Oh, I didn't see that.

I understand now! Thanks a ton.
