Calculate Log Base 40 of 20

To solve the equation log 40 (20) = 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 = 20, a = 40:
    log 40 (20) = log(20) / log(40)
  3. Evaluate the term:
    log(20) / log(40)
    = 1.39794000867204 / 1.92427928606188
    = 0.81209817529089
    = Logarithm of 20 with base 40
Here’s the logarithm of 40 to the base 20.
