13/33

Answer 2

     

$\Rightarrow\ \boxed{\frac{3^{40}+3^{39}+3^{38}}{3^{41}+3^{40}-3^{39}}} \\ \\ \\ \Rightarrow\ \boxed{\frac{3^{38+2}+3^{38+1}+3^{38}}{3^{38+3}+3^{38+2}-3^{38+1}}} \\ \\ \\ \Rightarrow\ \boxed{\frac{3^{38} \times 3^2+3^{38} \times 3+3^{38}}{3^{38} \times 3^3+3^{38} \times 3^2-3^{38} \times 3}} \\ \\ \\ \Rightarrow\ \boxed{\frac{3^{38}(3^2+3+1)}{3^{38}(3^3+3^2-3)}} \\ \\ \\ \Rightarrow\ \boxed{\frac{9+3+1}{27+9-3}} \\ \\ \\ \Rightarrow\ \boxed{\bold{\frac{13}{33}}}$
