Calculate Log Base 21 of 400

To solve the equation log 21 (400) = 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 = 400, a = 21:
    log 21 (400) = log(400) / log(21)
  3. Evaluate the term:
    log(400) / log(21)
    = 1.39794000867204 / 1.92427928606188
    = 1.9679488884267
    = Logarithm of 400 with base 21
Here’s the logarithm of 21 to the base 400.
