log

Result:

**log81 (40) = 0.83944069535807**.

## Calculate Log Base 81 of 40

To solve the equation**log**carry out the following steps.

_{81}(40) = x- 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) - Substitute the variables: With x = 40, a = 81:
log
_{81}(40) = log(40) / log(81) - Evaluate the term:
log(40) / log(81)
= 1.39794000867204 / 1.92427928606188 =
**0.83944069535807**=**Logarithm of 40 with base 81**

## Additional Information

- From the definition of logarithm b
^{y}= x ⇔ y = log_{b}(x) follows that 81^{0.83944069535807}= 40 -
