Log is short for "Logarithm". In mathematics, the logarithm is the inverse operation to exponentiation. That means the logarithm of a number is the exponent to which another fixed value, the base, must be raised to produce that number. In simple cases the logarithm counts repeated multiplication.
Example: The log of 100 to base 10=2. 2 means the number of times you multiply 10 by itself to give you 100. So, because the log is 2, then it we multiply 10 X 10=100. It is written like this:10^2=100.

Yes, what our guest has said is correct.
A logarithm is an index or an exponent or a power (3 words that mean the same thing)
You can use them if you need to find a missing exponent
For example
\(If\;\;3^x=243\\ then \;\;x=log_3 243\\ x=5\;\; because\;\;3^5=243\\~\\ \)
In words
If 3 to the power of x = 243 then x = log of 243 base 3
Most calculators can only to base 10 or base e and it is easy to change from one base to another but the web2 calc can work in any positive integer base. I will just check this ://
log(243,3) = 4.999999999999999 near enough 4.9 repeater actually is 5 anyway://
