   A challenging nested radical integral

   Greetings,   
      
   I was hoping the Risch-Trager-Bronstein algorithm of FriCAS and/or AXIOM would   
   compute the following integral in a reasonable amount of time   
      
   -> integrate((x+(4+x^2)^(1/2))^(-1/9)*(-2+2^(1/3)*(x+(4+x^2)^(1/   
   ))^(2/3))^(1/3),x)   
      
   Was it wishful thinking? My computer has been running FriCAS 1.3.6 for over an   
   hour. The answer to this integral does not require any logarithms, so it   
   should be computable with the algebraic extensions of Hermite reduction, right?
