What is the common logarithm of 10?$\begingroup$ Presumably you are summing some series to obtain $\ln 2$. Which one? Without knowing that there is no way to answer. If the series is alternating, as I suspect, you can get an upper bound from the alternating series theorem.Explanation: ln(x) is asking e to the power of what is x. In this case, e to the power of 2 is e2. thus, ln(e2) = 2. Another way is using the property of logarithms that says ln(ab) = b ⋅ ln(a) In this case, a = e and b = 2. Thus, ln(e2) = 2 ⋅ ln(e) = 2 ⋅ 1 = 2. Answer link.It is denoted by "ln". i.e., log e = ln. i.e., we do NOT write a base for the natural logarithm. When "ln" is seen automatically it is understood that its base is "e". The rules of logs are the same for all logarithms including the natural logarithm.
