...Logarithms constructed to the base 10 are called, for the sake of distinction, common logarithms. Hence, **the common logarithm of a number is the index of the power** of 10 which is equal to that number. The only other base to which logarithms have ever been constructed,... | |

...constructed upon the number 10 as a base. Hence, The common logarithm of a number, is the exponent **of the power to which 10 must be raised, in order to** produce that number. Thus, 3 is the logarithm of 1000, because 103 = 1000; and 0.5 is the logarithm... | |

...Hence, as x may be any positive number, and y its logarithm, we arrive at the conclusion, that the **logarithm of a number is the index of the power to which** the base of the system must be raised to produce that number. Thus, in the common logarithms, m which... | |
