How to find a log of a number using a table and where can i find this table?

I am appearing for an examination where I am not allowed to use calculator. I will be given a log table and asked to derive logs of specific number. And its not exactly log but rather 'ln', what is the difference between log and 'ln' and how to find 'ln' rather than log using some table. Also., where can i get this table to practice?How to find a log of a number using a table and where can i find this table?
ln means ... natural logarithm ... it has base ';e'; = 2.71828...



you need properties of logarithm then

since you will be given partial logarithms of certain numbers...

.. . .

log means the base is 10



some of the properties are

ln ab = ln a + ln a

ln (a/b) = ln a - ln b

ln (a^r) = r ln a

';ln'; means ';natural logarithm';, logarithms that use the number designated e (e≈2.71828) instead of base-10 (or ';common';) logs.



There is a table of natural logs available here:
