Calculate Log Base 81 of 243

To solve the equation log 81 (243) = 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 = 243, a = 81:
    log 81 (243) = log(243) / log(81)
  3. Evaluate the term:
    log(243) / log(81)
    = 1.39794000867204 / 1.92427928606188
    = 1.25
    = Logarithm of 243 with base 81
Here’s the logarithm of 81 to the base 243.

Additional Information

  • From the definition of logarithm b y = x ⇔ y = log b(x) follows that 81 1.25 = 243
  • 81 1.25 = 243 is the exponential form of log81 (243)
  • 81 is the logarithm base of log81 (243)
  • 243 is the argument of log81 (243)
  • 1.25 is the exponent or power of 81 1.25 = 243
