The logarithm (log (x)) of a number is the power that a fixed value, called a base, must be raised to produce that number.
For example: b y = x
Then : logb x = y ( b is the base)
Some important rules of Logarithms:
Logarithm power rule: logb(x y) = y ∙ logb(x)
Logarithm Calculator is a tool that calculates the log value of any positive real number with a given base.
