   Hi;   
      
   Not according to Rubi 4.3.   
      
   -------------------   
   Clear[t];   
   integrand = (1 + 40*t)*(1 + 4*t^2 + 81*t^4);   
   Assuming[t > 0, Int[Sqrt[integrand], t]]   
   ------------------   
      
   No evaluation. Same with Maple. can't do it. Neither can Integrate[]
