## Calculate Log Base 81 of 9

To solve the equation log 81 (9) = 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 = 9, a = 81:
log 81 (9) = log(9) / log(81)
3. Evaluate the term:
log(9) / log(81)
= 1.39794000867204 / 1.92427928606188
= 0.5
= Logarithm of 9 with base 81
Here’s the logarithm of 81 to the base 9.

• From the definition of logarithm b y = x ⇔ y = log b(x) follows that 81 0.5 = 9
• 81 0.5 = 9 is the exponential form of log81 (9)
• 81 is the logarithm base of log81 (9)
• 9 is the argument of log81 (9)
• 0.5 is the exponent or power of 81 0.5 = 9
BTW: Logarithmic equations have many uses in various contexts in science.
