From my experience with an 89Ti it is ♦9

Sorry TI89 users it is in the CATALOG as 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.

The graph of y=22log(10) is a straight line, though it should go through (0,0) and (1,22). Log(10) is a constant 1, so the function is simply y=22x .

If you want "twenty-two times log-base-ten of x", write it as 22*log(x) .

If you want "twenty-two times log-base-ten of x", write it as 22*log(x) .

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.

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.

If you want to take the log base b of x, enter it as log(x, b).

To get log, you can either type it in or press diamond 7.

Hello,

The wrong terminology is playing tricks on you.

Answer; antilog of 0.345 = 10^(0.345) =2.21309471

Look at the last two commands on the screen capture.

Hope it helps

Thanks for using FixYa

- If you are talking about the natural logarithms, the inverse function of the natural log is the exponential:
**ln(e^(x))=e^(ln(x)) = x** - If you are
**.**

Raise the base of your log to the power produced by the answer.

Example: If ln(x) = y, raise e (base of the natural logarithm) to the y to get x = e^y

Example 2: log(x) = y - x = 10^y

So if log(x) = 2, x = 10^2 = 100

Example: If ln(x) = y, raise e (base of the natural logarithm) to the y to get x = e^y

Example 2: log(x) = y - x = 10^y

So if log(x) = 2, x = 10^2 = 100

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, )

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

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.

There is no log (base 10) button on a TI-89. It's buried in the CATALOG as log(. As a shortcut, you can do ln(#)/ln(base), where # and base are replaced with what you want. For the inverse of a log, do the base raised to the part on the other side of the equals sign. So, log(x) = 2 would become 10^2 = x.
