## Calculate Log Base 81 of 7

To solve the equation log 81 (7) = 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 = 7, a = 81:
log 81 (7) = log(7) / log(81)
3. Evaluate the term:
log(7) / log(81)
= 1.39794000867204 / 1.92427928606188
= 0.44281093729036
= Logarithm of 7 with base 81
Here’s the logarithm of 81 to the base 7.

• From the definition of logarithm b y = x ⇔ y = log b(x) follows that 81 0.44281093729036 = 7
