for a; sufficiently small to insure convergence.   Expanding each member into negative powers of x and comparing coefficients, we pet
the first being equivalent to the usual formula for <KAT).   The general law can be represented symbolically by
where, after expanding the binomials, we are to replace N/(BP) by P_iN and any other term (BP)2*1"1 by jB2A-iP2A-i. It is easily shown that, if k is odd, ST?* is divisible by AT".
Silva26 used his symbolic formula, taking S to be the sum of 1, . . . , n, whence S(a) is the sum $n(l+n/A) of the multiples ^n of A. Thus 4>iM = Jft<M - This proof of Crelle's result is thus like that by Brennecke.162
W. Brennecke162 proved Crelle's result by means of
Set /x =<t>(n) , a = abc ....    He proved that
the signs being -{-or  according as the number of the distinct prime factors a, 6, ... of n is even or odd.
