Calculate Ln 9

To solve the equation ln(9) = 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 = 9, a = e:
    ln(9) = log(9) / log(e)
  3. Evaluate the term:
    log(9) / log(e)
    = 2.1972245773362 / 1
    = 2.1972245773362
    = Natural logarithm of 9.

Additional Information

  • From the definition of logarithm b y = x ⇔ y = log b(x) follows that e 2.1972245773362 = 9
  • e 2.1972245773362 = 9 is the exponential form of ln(9)
  • e is the logarithm base of ln(9)
  • 9 is the argument of ln(9)
  • 2.1972245773362 is the exponent or power of e 2.1972245773362 = 9
