The common antilog is the shifted function of the "log" button (marked 10-superscript-x) and the natural antilog is the shifted function of the "ln" button (marked e-superscript-x). The log and ln buttons are both on the third row of the keyboard.

He needs a math tables book. They may not be published anymore, but try an old book store. Also search online for "math tables". This site has some tables http://math2.org/,

You calculate the pH with the relation

pH=-log(c) where c is the value of concentration in mol/L.

ex: c[H+]= 3.57x10^(-6)

pH: (-) [LOG] 3.57 [2nd][EE] [(-)] 6 [ ) ]

Here you have 2 change sign key press [(-)]

If you have the pH, and want to calculate the concentration that yields that value of the pH you proceed as follows

c= 10^(-pH)

Ex pH=8.23

c: [2nd][LOG] [(-) 8.23 [)]

General shortcut.

If concentration is of the form c[H+]= 1*10^(-a) where a is an integer between 0 and 14, the pH is equal to the positive value of exponent.

Ex:c[H+]=1x10^(-5) Mol/L then the pH is just the positive value of the exponent, ie 5 because pH=-log(1.x10^-5) =- log1 -log(10^-5)=0 -(-5)=5

Above I use the rule log(axb)=log(a)+log(b) , the rule log(a^b) = b*log(a)and the facts that log(1)=0 and log(10)=1, the last being true if log stands for log in base 10.

The logarithmic functions have inverse functions that happen to have specific names. Even if the log^-1 notation may found on textbooks you will not find it on claculators.

Natural Logarithms LN. The inverse function of the natural logarithm is the EXPONENTIAL noted e to the x or e^x. On calculators the two functions usually share the same physical key. For example, LN is accessed directly and e^x is accessed with

The TI-83+ has keys for natural and common logarithms (base e and 10, LN and LOG, respectively). If you want to calculate the logarithm to another base, you have to use the relationship

LOGb(x) = LOG(x)/LOG(b) = LN(x)/LN(b)

LOGb(x) = LOG(x)/LOG(b) = LN(x)/LN(b)

It's 2*3=6 but about the base, you can't change it in the calculators the default base it's 10 so log x it's Logbase 10^x here some logs:

log x base y = log x / log y

log (x*y) = log x + log y

log (x/y) = log x - log y

in your example log 9 base 3 = log 9 / log 3 etc.

hope you get it, and it was helpful

Try 1/x button, does that give you the correct answer ? guessing the inverse ?

try switching the top button next to GT to rate,then enter your tax rate then % (8.25%) then switch the top button back to on (or whereever you had it set to) and hit the tax+ button. That worked for me. GO TEXAS!!!

I bought a classpad 300 plus but I dont know how to operate it. I saw some books for classpad 300 and I really want to buy some. However everytime I try to buy, there is always a classpad that goes with the books . Can I buy books for classpad with out buying a calculator anymore?
