Calculate Ln 400

To solve the equation ln(400) = 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 = 400, a = e:
    ln(400) = log(400) / log(e)
  3. Evaluate the term:
    log(400) / log(e)
    = 5.991464547108 / 1
    = 5.991464547108
    = Natural logarithm of 400.

Additional Information
