1. Answer:–

   Consider,

   a+b+c

   –––––––––––––––––––––––

   a-¹ b-¹ + b-¹ c-¹ + c-¹ a-¹

   = a+b+c

   –––––––––––––––––––––––––––––

   1/ab+ a/abc + b/cab

   [ multiply and divide each terms in the denominator by the missing terms. i.e., c,a,b respectively ]

   a+b+c

   = –––––––––––––––––––

   c+a+b

   –––––––––––––––––––

   abc

   = 1/1/abc

   =abc

   hence proved ........
