...indicated by r, of both members of (4), we have whence, by the definition, - = log \?m. (9.) That is, **the logarithm of any root of a number is equal to the logarithm of the number divided by the.** index of the root. The preceding principles enable us to abbreviate the operations of multiplication... | |

...log m ; then m = a*. Therefore m" = (a1)" = a** ; whence by definition, log mp = px = p log m. (7) **The logarithm of any root of a number is equal to the logarithm of the number divided by the** index of the root. For let x = log m ; then m = a1. 1 1 X Therefore m? = (a*)~r = ar ; whence by definition,... | |
