Calculate Log Base 2 of 81
To solve the equation log 2 (81) = 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 = 81, a = 2: log 2 (81) = log(81) / log(2)
- Evaluate the term: log(81) / log(2) = 1.39794000867204 / 1.92427928606188 = 6.3398500028846 = Logarithm of 81 with base 2
Additional Information
- From the definition of logarithm b y = x ⇔ y = log b(x) follows that 2 6.3398500028846 = 81
- 2 6.3398500028846 = 81 is the exponential form of log2 (81)
- 2 is the logarithm base of log2 (81)
- 81 is the argument of log2 (81)
- 6.3398500028846 is the exponent or power of 2 6.3398500028846 = 81
