Calculate Log 400

To solve the equation log (400) = x using a base distinct from 10 carry out the following steps.
  1. Apply the change of base rule:
    log a (x) = log b (x) / log b (a)
    With b = e:
    log a (x) = ln(x) / ln(a)
  2. Substitute the variables:
    With x = 400, a = 10:
    log (400) = ln(400) / ln(10)
  3. Evaluate the term:
    ln(400) / ln(10)
    = 8.74113642290101 / 2.30258509299405
    = 2.602059991328
    = Decimal logarithm of 400

Additional Information
