DefinitionWhen you evaluate a logarithm, you are basically simplifying a logarithmic expression to get an actual number, which will test your knowledge of the properties of logs as well as the individual number you are taking the log of. And if you need to remind yourself, logarithm is the power to which a number (called a base) must be raised to produce that number. Techniques involving tables or calculators to evaluate logarithms, or identities giving new ways of calculating logarithms from other logarithms. Logarithmic expressions are commonly used in setups of quantitative analysis such as functions, regressions, and integrated workings of calculus within mathematical and business environments. Ex: If an evaluation is made for log10100, this term would equal 2 because 102= 100 that is the reason of the logarithm to base 10 of 100 is 2
