The meaning of LOG is a usually bulky piece or length of a cut or fallen tree; especially : a length of a tree trunk ready for sawing and over six feet (1.8 meters) long. How to use log in a sentence.
e. In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 103, the logarithm base of 1000 is 3, or log10 (1000) = 3.
A log is a piece of a thick branch or of the trunk of a tree that has been cut so that it can be used for fuel or for making things. He dumped the logs on the big stone hearth. ...the original log cabin where Lincoln was born.

Logarithms made it easy for people to carry out otherwise difficult operations, eg: find the value of 4th root of 24. we can simply take log(24) and divide by 4. The antilog of the resultant figure will give us the answer.
A log is the trunk of a tree minus the branches: logging is cutting down trees. A log is also a written record of something, and logging is keeping such a record. The first type of log is a tree that's been cut down with the branches stripped.
About this unit. Logarithms are the inverses of exponents. They allow us to solve challenging exponential equations, and they are a good excuse to dive deeper into the relationship between a function and its inverse.
