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.

The value of 5 in logarithmic form is log(5) = 0.6989700043360189. If the base is 10, you want to know the power 10 must be raised to to equal 5. The answer is 10 to the 0.69897 (rounded) power equals 5. For most people, the easiest way to get this is to put =LOG(5) in an Excel spreadsheet.

We need to make it exactly the same as the base. So we're going to change this number 16.

In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 103, the logarithm base 10 of 1000 is 3, or log10 (1000) = 3.

Log: (in math) An abbreviation for logarithm. logarithm: The power (or exponent) to which one base number must be raised ? multiplied by itself ? to produce another number. For instance, in the base 10 system, 10 must be multiplied by 10 to produce 100. So the logarithm of 100, in a base 10 system, is 2.
