The natural logarithm is the logarithm having base e, where
The common logarithm is the logarithm to base 10.
It really depends on the question!
Maybe you should check out the examples!

The common, or Base-10, logarithm will cover any multiplication, division and power arithmetic in the ordinary numbers, which are to base-10. It is also the base for the logarithmic ratio defining the decibel scale used in acoustics and electrical signals analysis.

The natural logarithm (base-e) underlies a large number of specific scientific laws and purposes, such as the expansion of gas in a cylinder.
LN is typically the syntax used to represent the natural logarithm function. Although some programming languages and computer applications use LOG to represent this function, most calculators and math textbooks use LN. In use, it would look like this:y=ln(x)Which reads as "y equals the natural logarithm of x".The natural logarithm is a logarithm that has a base of e, Euler's number, which is a mathematical constant represented by a lowercase italic e (similar to how pi is a constant represented by a symbol). Euler's number is approximately equal to 2.718281, although it continues on far past six decimal places.Functionally, the natural logarithm can be used to solve exponential equations and is very useful in differentiating functions that are raised to another function. Typically, when the solution to an equation calls for the trivial use of a logarithm (that is the logarithm is only being used as a tool to rewrite the equation), either the natural logarithm or the common logarithm (base 10) is used.
The actual calculations to get a logarithm are quite complicated; in most cases you are better off if you look the logarithm up in tables, or use a scientific calculator.
To convert 0.19 into its natural logarithm (LN), you use the natural logarithm function, which is typically denoted as ln. You can calculate it using a scientific calculator or a programming language. The result for ln(0.19) is approximately -1.6607, indicating that 0.19 is less than 1, which results in a negative logarithm.
should we use natural gas and oil
If you are using a scientific calculator you will have a key labelled "log". To find the logarithm (to base 10) of a number, simply enter "log" followed by the number that you want to log. If you want a natural logarithm - log to the base e - use the "ln" key instead. If you haven't got a scientific calculator, use the one on your computer.
Natural logarithms use base e (approximately 2.71828), common logarithms use base 10.
You can use the change of base formula which is: logxb logab=--------- logxa
There are several methods. Euler could find the value of a logarithm by doing a search using the geometric mean, arithmetic mean and a table. There is a series using that natural log that can be converted into base 10. I have my own method which is in the "related links" section.
well it is safer dah
Here is an excellent link upon this subject. http://www.oldcomputers.arcula.co.uk/bhist3.htm
The main use for a logarithm is to find an exponent. If N = a^x Then if we are told to find that exponent of the base (b) that will equal that value of N then the notation is: log N ....b And the result is x = log N ..........b Such that b^x = N N is often just called the "Number", but it is the actuall value of the indicated power. b is the base (of the indicated power), and x is the exponent (of the indicated power). We see that the main use of a logarithm function is to find an exponent. The main use for the antilog function is to find the value of N given the base (b) and the exponent (x)
You should use the camera flash when there is not enough natural light to properly expose the subject you are photographing.
