### TI BA 2 Plus Calculator: Cannot figure out how to use log(10) function, not the natural log but the base of 10 log

The BA II+ does not have a key for the common logarithm function. You can calculate the common log of a number by calculating its natural log and then dividing by the natural log of 10.

log10(x) = ln(x)/ln(10)

The same procedure works for logarithms to any base.

### How do I find the "Log" key on the TI BA 2 Plus? Not natural log, but to the base of 10

There is no common logarithm key. You can compute the common (base 10) log of any number by using the relationship log(x) = ln(x) / ln(10).

For example, to compute the log of 2, type 2 LN / 1 0 LN =

### How to find log on a calculator

Since I do not know what Kenko calculator you have I will remain general.

Locate a key marked log (for common decimal logarithm)
Try the two options. One of them is bound to work
1. Enter a positive number and press the key marked LOG.
2. If that does not work, press the LOG key and then enter a positive number. If the calculator displayed log( , with a left parenthesis, insert a right parenthesis before pressing the = key.
To calculate the natural logarithms (LN), look for a key marked with LN and proceed as for the common logarithm. I am sure that the syntax (key sequence) that works for the common log will work for th natural log.

If no key is marked on top of it with LOG or LN, it may be because those markings are ON the body of calculator. In that case the functions are accessed by pressing a key marked SHIFT or 2ND, or 2ndF before the function LOG or LN.
