comment What algorithm is used by computers to calculate logarithms?
@stackoverflowuser2010: Yes, they aren't (see earlier comments). I haven't found the time to find new links, sorry :-(. The title of the question: "What algorithm is used by computers to calculate logarithms?". It worked when the question was posted, three years ago...

comment Root Calculation by Hand
@anorton: I actually don't remember the reason. But a starting guess for the root is a good guess. It also includes 2 and 5, which typically lead to easier calculations. Also, to use binomial theorem, the guess $g$ you make must satisfy $\frac{|105 - g^5|}{g^5} < 1 $ and the closer to zero that is, the fewer terms you have to compute.

comment If $\displaystyle\lim_{n\to\infty}{\dfrac{a_n}{1+|a_n|}}=0$ then $\displaystyle\lim_{n\to\infty}{a_n}=0$
If $b_n = \frac{|a_n|}{1+|a_n|}$ then can you write $|a_n|$ in terms of $b_n$?

comment Root Calculation by Hand
@MonK: You can compute it by hand. For instance: en.wikipedia.org/wiki/Long_division.
