Suppose you want to divide x by y
Find log(x) and log(y) to any base b (usually 10 or e)
Calculate z = log(x) - log(y)
Look up the antilog of z (or find the number whose log is z).
x/y = antilog(z)

whats is the mantissa of logarithm
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.
That is a logarithm to the base "e", where "e" is a number that is approximately 2.718.
The fractional part of a logarithm is called the Mantissa.
