Answer 1

Hello Mate!

$\frac{5 {(81)}^{n + 1} - {3}^{4n + 5} }{3 \times {3}^{4n} + {(81)}^{n} } \\ \frac{5 \times {3}^{4n + 4} - {3}^{4n + 5} }{3 \times {3}^{4n} + {3}^{4n} } \\ \frac{ {3}^{4n} \times {3}^{4 } \times 5 - {3}^{5} \times {3}^{4n} }{3 \times {3}^{4n} + {3}^{4n} } \\ \frac{ {3}^{4n} (405 - 243)}{ {3}^{4n} (3 + 1)} \\ \frac{162}{4} = 40.5$

Hope it helps☺!
