Calculate Ln 13

To solve the equation ln(13) = 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 = 13, a = e:
    ln(13) = log(13) / log(e)
  3. Evaluate the term:
    log(13) / log(e)
    = 2.5649493574615 / 1
    = 2.5649493574615
    = Natural logarithm of 13.

Additional Information

  • From the definition of logarithm b y = x ⇔ y = log b(x) follows that e 2.5649493574615 = 13
  • e 2.5649493574615 = 13 is the exponential form of ln(13)
  • e is the logarithm base of ln(13)
  • 13 is the argument of ln(13)
