77!*(77!-2*54!)^3/(77!+54!)^3 + 54!*(2*77!-54!)^3/(77!+54!)^3

• after evaluating the given problem we get
  (77!-54!)*(77!+54!)^3/(77!+54!)^3=(77!-54!)
  let 77!=a;
  and 54!=b;
  it becomes a simple alzebra.

• take 77!=a
  and 54!=b
  now the given expression will look like
  (a(a-2b)^3 )/(a+b)^3 + (b(2a-b)^3 )/(a+b)^3
  
  ( a (a^3 - 6a^2 b + 12ab^2 - 8b^3) + b (8a^3 - 12a^2 b + 6ab^2 - b^3) ) / (a+b)^3
  (a^4 - 6a^3 b + 12 a^2 b^2 - 8ab^3 + 8a^3 b - 12a^2 b^2 + 6ab^3 - b^4) / (a+b)^3
  (a^4 + 2a^3 b - 2ab^3 - b^4) / (a+b)^3
  ( a^4 - b^4 + 2ab(a^2 - b^2) ) / (a+b)^3
  ( (a^2 + b^2)(a^2 - b^2) + 2ab(a^2 - b^2) ) / (a+b)^3
  ( (a^2 - b^2) (a^2 + b^2 + 2ab) ) / (a+b)^3
  ( (a^2 - b^2)(a+b)^2 ) / (a+b)^3
  ( (a+b)(a-b) (a+b)^2 ) / (a+b)^3
  ( (a+b)^3 (a-b) ) / (a+b)^3
  a-b
  i.e 77! - 54!
