Nettetlet $f(n)$ be the log function of n. So a general log function can be written as $f(n)=k\log n +c$ where $k$ and $c$ are constants $\implies 255=k\log {10^6}+c$ and $0=k\log … NettetFrom the change of base theorem, log base a of b = (ln b)/ (ln a). For example, you can calculate log base 3 of 5 by calculating (ln 5)/ (ln 3) which should give approximately 1.465. (Note that if your calculator also has a log key, another way to calculate log base 3 of 5 is to calculate (log 5)/ (log 3).

NettetFirst, visualize our scale as being on a ruler, where each number is 1 cm apart. In a base ten logarithmic scale, 2 cm on the scale corresponds to 10² (100). 3 cm corresponds to 10³ (1000). Obviously, if we change the base of the logarithm, the spacing between each number doesn't matter, it is always one cm between each one.
