Calculate Log Base 81 of 399

To solve the equation log 81 (399) = x carry out the following steps.
  1. Apply the change of base rule:
    log a (x) = log b (x) / log b (a)
    With b = 10:
    log a (x) = log(x) / log(a)
  2. Substitute the variables:
    With x = 399, a = 81:
    log 81 (399) = log(399) / log(81)
  3. Evaluate the term:
    log(399) / log(81)
    = 1.39794000867204 / 1.92427928606188
    = 1.3628469021019
    = Logarithm of 399 with base 81
Here’s the logarithm of 81 to the base 399.
