and what if u want to find log of a no with base other than 10?

campbell_st · Answer

you would need to use change of base... 

$$\log_{a}{b} = \frac{\log_{10}(b)}{\log_{10}(a)}$$

this will allow you to find the log of any number in any base. 

its works the same if you use base e rather than base 10...
