Use the equivalent formula log base b of a is equal to [log10(a)]/[log10(b)], you can also use ln(a)/ln(b), the results will always be equivalent

SOURCE: Random based logarithms

to do logarithms with other bases, use change-of-base. let's say you want to do log base 5 of 25. for clarity i'll write this as log(5) 25. you would have to do log(10) 25 / log(10) 5 to get 2. key sequence: [LOG], 2, 5, ), / (divide), [LOG], 5, )

Logarithm


The Casio FX-300MS does not provide base 2 logarithms as a single key operation. However, you can use the natural logarithm (ln, base e = 2.7182818...) and the formula

log2 ( x ) = ln( x ) / ln( 2 )

To calculate the base 2 logarithm of 16, key in
[ln] 16 [/] [ln] 2 [=]
and get displayed the correct answer 4.

The same simple formula also works for any other base, and actually for any other logarithms provided by your calculator. The FX-300MS also provides a logarithm to base 10 (lg). You could also
type
[lg] 16 [/] [lg] 2 [=] to get the solution to the problem above, or
[lg] 25 [/] [lg] 5 [=] to get the base 5 logarithm of 25.

Change base log


The TI 86 has two logarithmic functions: natural logarithm (ln) and common (decimal) logarithms (log). If you need the logarithm in any other base than e or 10 you need to use one of the two equivalent expressions
log_b(x) =ln(x)/ln(b) =log(x)/log(b)
Here b is the value of the base of the logarithm and x is the argument (the value whose logarithm you are seeking). Of course the argument x must be a positive number.
Note: On the TI 86 the log function can calculate the logarithm of a complex number, according to the manual.

TI-84 Calculator Gives Me the Wrong Logarithm Solution


"log(2)8" means "common logarithm of 2 multiplied by 8".

The TI-84 has three different logarithm functions.
log is the common (base-10) logarithm.
ln is the natural (base-e) logarithm.
logBASE lets you take the logarithm to any positive base.

If you want the log base 2 of 8, you want logBASE(2,8). You'll find the logBASE function in the catalog, accessible by pressing 2ND [CATALOG] ). CATALOG is the shifted function of the 0 key, the ) gets you to the Ls in the catalog.

Where can I find the log values in TI 89


For natural logarithms, you can use the ln function (2ND shift of the X key). For example, the natural logarithm of 3 is 2ND [LN] 3 ) ENTER.

For logarithms to other bases, use the log function (diamond shift of the 7 key). For example, the base-2 logarithm of 16 is diamond 7 1 6 , 2 ) ENTER. If the base is 10 (common logarithms), you can omit the comma and the second argument.

That's the base for the logarithm. Logarithms are usually taken with base 10 (common logarithms, LOG on the calculator) or with base e (natural logarithms, LN on the calculator), but sometimes other bases are used.

Using the correct key combination to determine inverse log


Hi,
Sorry to contradict you but there are many types of logarithms, the most important ones are
  1. the common logarithms (log in base 10),
  2. the natural logarithms (logarithms in base e)
  3. the binary logarithms (logarithms in base 2)
On calculators, the common logarithms are labeled [LOG], and the natural logarithms are labeled [LN].

The inverse function of the natural log function is the exponential (e^(x)), and the inverse of the log in base ten function is the function ten to the power of. It is called (sometimes) the antilog

Ex:
Question What is the antilog of 3.5678?
Answer The antilog of 3.5678 is 10^(3.5678) = 3696.579068
Verification: log(3696.57908) =3.5678

Hope it helps.

How to use the Logerithmic function on this calculator


Hi,

Logarithms in base 10 :Common logarithms
  1. The calculator has a key labeled [LOG]. It allows you to calculate the common logarithms (logarithms in base 10).
  2. To calculate the common logarithm of a (positive) number you type in the number, press the [LOG] key .
  3. Ex: 15.32 [LOG][=] gives 1.1852558765
Logarithms in base e : Natural logarithms
  1. The calculator has a key labeled [LN]. It allows you to calculate the natural logarithms of positive numbers.
  2. Ex: natural log of 15.32 is entered as
  3. 15.32 [LN] gives 2.729159164
Hope it helps.
Don't forget to rate the solution and don't be stingy: 4 thumbs up won't leave you any the poorer.
