2/3 is ur answer

Answer 2

$\sf \frac{3^{40} + {3}^{39} }{ {3}^{41} - {3}^{40} }$

Let us Factories the given expression

$\therefore \sf \: \frac{(3 + 1) \times {3}^{39} }{(3 - 1) \times {3}^{40} } \\ \\ = \frac{4}{2} \times \frac{1}{ {3}^{(40 - 39)} } \\ \\ = \frac{4}{2} \times \frac{1}{3} \\ \\ = \frac{4}{6} \\ \\ = \frac{2}{3}$

Answer is 2/3 i.e. 0.66666
