For a 1 the logarithm of b to base a is x if a x b. F x 1 x lnb x is the function argument. Logarithm Formula for positive and negative numbers as well as 0 are given here.
Many derivations of physics are possible only due to Logarithm Formula.
The result 19345 is the power to raise the base 10 to equal 86. B is the base. In mathematics the logarithm is the inverse function to exponentiationThat means the logarithm of a given number x is the exponent to which another fixed number the base b must be raised to produce that number xIn the simplest case the logarithm counts the number of occurrences of the same factor in repeated multiplication. Log b a 1 log a b where abare positive real numbers a61 b61 28.
