Use a scientific calculator. The actual calculation is rather involved; it is based on infinite sums (you add up several terms, until you get the desired accuracy). If you every study calculus, you will learn about that.
The natural logarithm is the logarithm having base e, whereThe common logarithm is the logarithm to base 10.You can probably find both definitions in wikipedia.
To find a logarithm, you need to determine the power to which a given base must be raised to produce a specific number. The logarithm can be expressed as ( \log_b(a) = c ), meaning ( b^c = a ), where ( b ) is the base, ( a ) is the number, and ( c ) is the logarithm. You can use logarithm tables, calculators, or software tools to compute logarithms for various bases, such as base 10 (common logarithm) or base ( e ) (natural logarithm).

whats is the mantissa of logarithm
You look the number up in a table.Example:Find the logarithm of 511From a table I see that numbers are only listed from 1.00 to 9.99I look up 5.11 and know that I have to multiply that by 100 or 102 to get my original value, which is equivalent to adding 2 to the table value.The table gives me 0.7084209 for the logarithm for 5.11The logarithm of 511 is thus 2.7084209For numbers less than 1 the logarithm will be negative!Negative numbers do have logarithms!
Take the logarithm of 500, half it, then take the antilog.
Take its logarithm, divide that by 2 and take the antilog of your answer....
Take the logarithm of your number, divide it by 3 then take the antilog.
To calculate a logarithm using the natural logarithm (ln), you can use the relationship between logarithms of different bases. The natural logarithm is specifically the logarithm to the base (e), where (e \approx 2.71828). To convert a logarithm of another base (b) to natural logarithm, you can use the formula: (\log_b(x) = \frac{\ln(x)}{\ln(b)}). This allows you to compute logarithms in any base using the natural logarithm.
The common logarithm (base 10) of 2346 is 3.37. The natural logarithm (base e) is 7.76.
The base 10 logarithm of 0.01 is -2.
