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.

Everytime i sign in my password to read someones msg,it says i have a wrong password,everytime this happens,they clear me and i use that password after i have changed to my password,and then the very next...

I haven't had to do this with Facebook in a while, but you might want to double check a couple of things. 1st) make sure that if they are giving you a replacement password that you log in with that password and before you log out you go to your Facebook profile an update your profile with a new password of your chooing: following, of course, any rules Facebook has about the length and make-up of a new password. In other words if they require that your new password has to have more than 8 characters but less than 16 and must have at least at least one alpha, one numeric, and one capital that you create a new password matching those requirements. If they give you a password to log in with, it is just a temporary password and is only intended to be used once to allow you the opportunity to create a new password. Once you log in with the temporary password it expires and if you don't create a new one while you are logged in, you won't be able to log back in with out going through the entire process again. 2nd) Make sure that when you create a new password that you do not have the capslock key engaged. This can lead to all sorts of confusion as you are essentially reversing all your upper and lower case letters if the capslock key is on. I hope this helps. Good luck.

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

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
your example answer is about 0.919... if i get right what did you write.
Glad to help :)
