What are logarithms used for?

Logarithms are the inverse of exponents. A logarithm (or log) is the mathematical expression used to answer the question: How many times must one “base” number be multiplied by itself to get some other particular number? For instance, how many times must a base of 10 be multiplied by itself to get 1,000?

How are logarithms used in real life?

Much of the power of logarithms is their usefulness in solving exponential equations. Some examples of this include sound (decibel measures), earthquakes (Richter scale), the brightness of stars, and chemistry (pH balance, a measure of acidity and alkalinity).

Characteristic Part= 2 and mantissa part= 872

  • Check the row number 28 and column number 7. So the value obtained is 4579.
  • Check the mean difference value for row number 28 and mean difference column 2.
  • Add the values obtained in step 2 and 3,we get 4582.
