Question about Casio FX-300MS Calculator

The common (base-10) antilog is the shifted function of the "log" key on the third row of the keyboard, just above the "cos" key. The natural (base-e) antilog is the shifted function of the "ln" key just to the right of the "log" key. The two antilogs are marked "10^x" and "e^x", respectively.

hi

to explain what a logarithm is, it's to involved to explain here but check sosmath.com for a detailed explaination of it

i use it to find root and powers of numbers. it turn up in certain natural process like radioactive decay, population growth, interest calculations..etc

for square rooting a number

square root of 16

type 16 press the log ( I'm using a scientific calculator a TI 30s to be exact) key to get 1.204119983 for a result divide by 2 to get .602059991 press shift or 2nd log key ( to get the 10^ key - this the anti- log key) to get 4 as a result

I hope this helps

The common antilog is marked 10-superscript-x and available as the shifted function of the log key. The natural antilog is marked e-superscript-x and available as the shifted function of the ln key.

press the alpha button and then the log to calculate antilog

Depending on the actual log function you are talking about, the inverse function (what you call the anti log) can be one of several things.

The inverse of the natural log (LN) is the exponential function** e^x**.

**If y= ln(x) then x=e^y **

On a calculator functions that are inverse of one another share the same physical key.**If one function is marked on a key, the inverse function is usually the SHIFTED (or 2nd) key **

The inverse of the common (decimal logarithm) is the power function with 10 as base.

Example:** if y= log(x) then x=10^y**

For an arbitrary base (must be positive)** if y= log_b(x) then x=b^y**.

Note: I do not think that the FX-300ms can perform log calculations in bases other than e (natural log) or 10 (common decimal log).

What you call the antilog is also known as as the power function. More specifically, the inverse of a decimal log is the function 10 to a power, (10^x) It shares the same physical key as the log function. If the calculator has a key marked [LOG] you have to press the [2nd or SHIFT] key followed by the [LOG] key to activate the anti-log.

For natural log (logarithms in base e) the antilog is the exponential function (e^x). It shares the same physical key as the [LN] function.

Sorry the answer comes too late for your final exam. If you took the time to really understand what the inverse of a log function is, you would have saved yourself the anxiety before the test.

Anyway, the inverse of the logarithm in base 10 IS the power function with base 10.

y=log(x) <=> x=10^(y).

Some calculator manufacturers use the marking ^-1 to represent an inverse function. But recently one sees new calculators with the new notation.

By the way, the inverse of the natural log function (LN) is the exponential function (e^(x))

If Log y = x, then y = e^x. That is e^(log x) = y. So if you want the anti-log of 12, you just punch in e^12. That's assuming we're using the natural logarithm. If it were base 10 it would be 10^12, if it's base 2, it would be 2^12, etc.

Anti log will be shown as 10^x (10 raised to power x)
For natural log it's e^x
I think it's shift > log

Use the inverse log key sequences "2nd LN" or "2nd LOG" depending on whether you are using natural logs or logs to base 10
