Class 9 math logarithm table 1 to 100. Logarithms had originally developed to simplify complex arithmetic calculations they designed to transform multiplicative processes into additive ones. In this case 10 2 yields you 100. Logarithm the exponent or power to which a base must be raised to yield a given number. So 2 is the exponent value and the value of log 10 100 2.

Since 2 6 2 2 2 2 2 2 64 6 is the exponent value and log 2 64 6. What is the value of log 10 100. Identify the characteristic part and mantissa part of the given. Expressed mathematically x is the logarithm of n to the base b if b x n in which case one writes x log b n for example 2 3 8.

The logarithm is denoted in bold face. For instance the first entry in the third column means that the common log of 2 00 is 0 3010300. Logarithms of the latter sort that is logarithms. It is not always necessary to find the logarithm of a number by mere calculation.
