...first member to a form in which it shall also be divisible by the same factor. Since the logarithm of a **fraction is equal to the logarithm of the numerator, minus the logarithm of the denominator** (Art. 361), therefore, log. (14*)- log. (14*)= log. ( j±j? ) . But, by division, we find ^J=l-\-~... | |
