Inverse Logarithm. Logarithm of a number is defined as the power, that is raised to a fixed value called base, is raised to get that particular number. For example: 10$^{2}$ = 100, then log$_{10}$100 = 2. Inverse logarithm is the inverse of logarithm function. It is opposite to logarithm.
Natural Logarithm - ln(x) Natural logarithm is the logarithm to the base e of a number. Definition of natural logarithm. Ln as inverse function of exponential function. The natural logarithm function ln(x) is the inverse function of the exponential function ex. For x>0, f (f -1(x)) = eln(x) = x. Or. f -1(f (x)) = ln(ex) = x. Natural logarithm rules and properties.
