What does it give you? What is this 10exp11?
If you want to enter 7.8X10^11 type it as 7.8[EE]11. [EE] is the key [Exp[, or [EE] or [x10X]. The EE is a short cut for *10 to a power. The 10 must not be appear in the expression entered.

a 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

### Casio fx-83GT PLUS gives wrong values for logs

Are you using the right type of logarithms? The calculator provides for two types: common (base 10) and natural (base e).

Could you post an example or two, with the answers you get and the expected answers?

### How do you find the logarythm of log 4^1/64

I believe you will have to calculate part of this then input the rest of it. So one way to do this would be
to press [1/x] [6] [4] get an answer of .015625. Clear the calculator then press [4] [y^x] then put in the previous answer .015625 then [log] . This should give you .009407.

### My log functions are wrong

Hello,
It would help to know what you are trying to do or at least in what way you answers are wrong. I will do my best to guess right.

Ex: if you enter log(25) it gives you 2*log(5) and if you enter log(5) it echoes the same thing. If that is waht you get, it is easy to fix.
Press the Main icon at the bottom of the screen to open the calculator run screen. Unfold the first Menu to the left of Edit. Press Settings (first submenu) Press the/arrow and select Setup item, then Basic Format. Under Common tab you have the different formats: folder, display, angle, and Advanced. Put a check mark in the box to the left of Decimal Calculation an press Set to save configuration.

The other possibility is that you actived the 2D keyboard which gives you access to the 2d Function templates. You use these to calculate the log in arbitrary bases. Functions on this keyboard have a dark rectangle. If that is the source of your problem, use the stylus to select the mth keyboard.
Hope it helps.

### To solve the problem using log

Look the calculators has a default base 10 and you can't change it but you may learn this:
log x base y = log x / log y
log (x*y) = log x + log y
log (x/y) = log x - log y
so instead input log 8 base 2 you need to input log 8 / log 2
