Logarithm
From Wikipedia the frea encyclopedia
In mathematics the logarithm is the inverse operation to exponentiation That means the logarithm of
numberis the exponent to which another fixed value the base
must be raised to produce that number In
sirnple Cases the logarithm counts repeated multiplication Fot example the base 10 logarithm of 1000 is 3

10 = 103); the multiplication

generally exponentiation allows any positive real number to be raised to any rea
power, always producing
positive result 50 the logarithm car be calculated or any two positive rea
