    L. H. S  =   am / an  . b n / bl  . C l / c m

                   [ x m+n yl  ] m  . [ x n+l y m ] n . [ x l+ m yn ]l

               =------------------------------------------------

                   [ x m+n  yl  ]n ​​​​​​. [ x n+l . y m ] l  [ x l + m  yn ]l 

    multiply  m+n with  m,  l with m,  n+ l with n,  m with n 

    then split  numerator and denominator 

    all terms will cancel and remain 1

    .....thank you 

    all the best
