If it's a scientific calculator with a button labeled "Ln," you probably just need to type in the number you want to take the natural log of, and then hit the "Ln" button.
If the calculator does not have a "Ln" button, but it has a "log" button for log base 10, you can still calculate the natural log using the "change of base" formula. Let's write "log base a of b" as log_a(b). Then log_a(b) = log_c(b) / log_c(a). You want to take log_e(x), the natural log of a number x. That's equal to log_10(x) / log_10(e). With the calculator that has a log button but not a Ln button, you can take the log base 10 of e and of the number you want to take the natural log of, and then use division to get the final answer. Just take the base ten log of the number, and divide it by the log base ten of e.
Of course, you can also use Yahoo! to find that ln(794) = 6.6770834612 and ln(739) = 6.6052979209.

There are several possibilities, depending on your calculator.
Easiest is if your calculator has the natural log function: it will be a button labelled 'ln'. If so First type in your number, then hit the button. Your result will be displayed.
If your calculator does not have the natural log 'ln' function but has the log (base 10) function. Then you can make use of the fact that:
ln x = log10(x) / log10(e) ; where e=2.71828
Finally, if your calculator doesn't have any of the log functions but has the general exponential function (y^x) (on the button it would be a regular 'y' with a little 'x' at the upper right corner of the 'y', then you can figure on the ln by trial and error: Plug 2.71828 into memory (if you have that function to save retyping it over and over again) and guess the value for you ln. Calculate 2.71828^Guess, and see if you are right. If your result is too low, increase your guess, if your result is too high decrease your guess. This is a bit tedious, but I tested it out and it does not take that long to calculate the value.
If your calculator has none of the functions described above, there are other ways to proceed (Taylor expansions), but in that case I would suggest getting a new calculator.

You mean ln 794 or ln 739?
it's USUALLY near the [log] button. At least mine is. [ln] + [739].
Does that answer your question?
