. How to find log of any number
There are three properties of logarithm:
log(mn)=log m + log n
log(m/n)=log m - log n
Sometimes, When there's no log table around you, the most effective thing you obtain is your mind.
Here is a way which may be used to calculate the logarithm of more than a few if there's no log table to use.
This is likewise useful if the number is just too big to be calculated by a calculator.
First of all, recall the subsequent fundamental log values (it's no damage to recall those despite the fact that you have a log table).
These four values can be applied to calculate the log of any number.
The formula to calculate:
log (a+b)=log a +b /(2.42×a)
We have explained the main method to find any log value.
