Use Table Log For Free

If you know the values of logp for every prime, these can be used to determine the logarithm of any positive rational number just by using the rules log(ab)=bloga and log(ab)=log(a)+log(b). And if you don't remember what log(2) is, remember 210=1024?1000, therefore 10log(2)?3, or log(2)?0.3.

How to Use Logarithm Table? Step 1: Choose the value from the table. ... Step 2: Determine the number's decimal and integer parts. ... Step 3: Visit the common log table and check the intersections below for the cell value: Step 4: Utilize the Common Logarithm table with a mean difference at all times.

The log base 2 to a number N in algebra is equal to the exponent value of 2 which gives the number N. The log base 2 is written in the logarithmic form as log2N=k l o g 2 N = k , and the same is written in exponential form as 2k = N.

Here are the steps to find the logarithm of any number using the logarithm table. Step - 1: Find its characteristic (no need for a log table here). Step - 2: Find its mantissa (use log table). Step - 3: Add both characteristic and mantissa.

Look up the logarithms of the two numbers you want to multiply. Use the method above to find the logarithms. For example, if you want to multiply 15.27 and 48.54, you would find the log of 15.27 to be 1.1838 and the log of 48.54 to be 1.6861. Add the two logarithms to find the logarithm of the solution.

Since the base is also 10, we get log(2) = 3*0.1. = 0.3. This is a very accurate value as the value we obtain using a calculator is 0.301. We can use the expansion formula of the natural logarithm to find the value of ln(2).
