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

• assume a=77!& b=54!
  according to the expression
  (a(a-2b)^3)/(a+b)^3 + (b(2a-b)^3)/(a+b)^3)
  =(a^4+2*a^3*b -2*a*b^3-b^4)/(a+b)^3
  = (a-b)*(a+b)^3/(a+b)^3
  = (a-b)
  = (77!-54!)

• 77!-54!
  solve- ((a(a-2*b)^3)/(a+b)^3)+(b((2*a-b)^3)/(a+b)^3) and replace
