### High School Mathematics3.6 Characteristic and Mantissa of a Logarithm

 Logarithms of numbers contain integral and decimal parts. The integral part of the logarithm of a number is called the characteristic and the decimal part is called mantissa. If a number has 'n' digits the characteristic of its logarithm is 'n-1'. Example: log 3 = 0.4771. In the above '0' is characteristic, and .4771 is mantissa. Directions: Solve the following problems. Also write at least ten examples of your own.
