### 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.

### Cant find the Log function on the EL 733A

There is no common logarithm function on this calculator. However, you can calculate it easily enough using the natural logarithm function (ln). The log of x is equal to ln(x) / ln(10). In words, calculate the log of a number by calculating its ln then dividing by ln of ten.
