Calculate Ln 123

To solve the equation ln(123) = x carry out the following steps.
  1. Apply the change of base rule:
    ln (x) = log b (x) / log b (a)
    With b = 10:
    log a (x) = log(x) / log(a)
  2. Substitute the variables:
    With x = 123, a = e:
    ln(123) = log(123) / log(e)
  3. Evaluate the term:
    log(123) / log(e)
    = 4.8121843553724 / 1
    = 4.8121843553724
    = Natural logarithm of 123.

Additional Information
