Calculate Log Base 90 of 81

To solve the equation log 90 (81) = 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 = 81, a = 90:
    log 90 (81) = log(81) / log(90)
  3. Evaluate the term:
    log(81) / log(90)
    = 1.39794000867204 / 1.92427928606188
    = 0.97658556175108
    = Logarithm of 81 with base 90
Here’s the logarithm of 90 to the base 81.
