Calculate Log Base 81 of 91
To solve the equation log 81 (91) = x carry out the following steps.- 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 = 91, a = 81: log 81 (91) = log(91) / log(81)
- Evaluate the term: log(91) / log(81) = 1.39794000867204 / 1.92427928606188 = 1.0264903171586 = Logarithm of 91 with base 81
Additional Information
- From the definition of logarithm b y = x ⇔ y = log b(x) follows that 81 1.0264903171586 = 91
- 81 1.0264903171586 = 91 is the exponential form of log81 (91)
- 81 is the logarithm base of log81 (91)
- 91 is the argument of log81 (91)
- 1.0264903171586 is the exponent or power of 81 1.0264903171586 = 91
