Important formulas on Logarithm


  1. In mathematics, the logarithm is the inverse function to exponentiation. That 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 x. A logarithm is only the power that you have to raise some number ("the base"), to get some other number.

    For example, if you're working with logarithms to the base of ten, then log(1000) is 3 because I have to raise ten to the power of three to get 1000.

    This is all just a fancy way of expressing the fact that 10 x 10 x 10 = 1000, noting that I had to multiply ten by itself three times over. Thanks for sharing this beneficial information and formula.
