Calculate Ln 81
To solve the equation ln(81) = x carry out the following steps.- Apply the change of base rule: ln (x) = log b (x) / log b (a) With b = 10: log a (x) = log(x) / log(a)
- Substitute the variables: With x = 81, a = e: ln(81) = log(81) / log(e)
- Evaluate the term: log(81) / log(e) = 4.3944491546724 / 1 = 4.3944491546724 = Natural logarithm of 81.
Additional Information
- From the definition of logarithm b y = x ⇔ y = log b(x) follows that e 4.3944491546724 = 81
- e 4.3944491546724 = 81 is the exponential form of ln(81)
- e is the logarithm base of ln(81)
- 81 is the argument of ln(81)
- 4.3944491546724 is the exponent or power of e 4.3944491546724 = 81
