What is log 5? How can we find logs of numbers without using a calculator?
Logs (or) logarithms are nothing but another way of expressing exponents.
Answer: The value of log 5 is 0.6990
With the help of basic logarithmic properties, we will find the value of log 5
The easiest and fastest way to calculate the value of log 5 is with the help of a logarithmic table.
According to the logarithmic table, value of log 5 = 0.6990
Also, with the help of the logarithmic formula log (A/B) = log A - log B we can calculate value of log 5
As, log 5 = log (10/2)
= log 10 - log 2 (Since, log(A/B) = log A - log B)
And we know log 10 = 1 ; log 2 = 0.3010
So, log 5 = 1 - 0.3010
log 5 = 0.6990
log 5 can also be calculated using the logarithmic calculator.
Thus, the value of log 5 is 0.6990
