LOGARITHMS

INTRODUCTION

One of my normal reporters, Yousuf, as of late turned out to be extremely confounded over what "log" implied. He'd missed a little, however basic bit of data − that if the base is overlooked, it's expected we are discussing log base 10

So "log" (as written in math course readings and on number crunchers) signifies "log10" and talked as "log to the base 10". These are known as the normal logarithms. 

We utilize "ln" in math course books and on number crunchers to signify "loge", which we say as "log to the base e". These are known as the common logarithms.

DEFINITION

In mathematics, the logarithm is the reverse operation to exponentiation. That implies the logarithm of a number is the type to which another settled worth, the base, must be raised to deliver that number

EXPLANATION

A logarithm is simply an exponent that is written in a special way.

For example ,we know that the following exponential equation is true:

32 = 9

In this case, the base is 3 and the exponent is 2. We can write this equation in logarithm form (with identical meaning) as follows:

             log 3 9 = 2

We say this as "the logarithm of  9 to the base  3 is  2". What we have viably done is to move the type down on to the primary line. This was done generally to make duplications and divisions less demanding, however logarithms are still extremely convenient in mathematics
