plz tell me quickly .....​

Answer 1

Answer:

n=3

Explanation:

$\frac{ {9}^{n} \times {3}^{5} \times (27) ^{3} }{3 \times (81) ^{4} } = 27 \\ \frac{3^{2n} \times{3}^{5} \times(3^{3} ) ^{3} }{3 \times ( {3}^{4} )^{4} } = {3}^{3} \\ \frac{ {3}^{2n} \times {3}^{5} \times {3}^{9} }{3 \times {3}^{16} } = {3}^{3} \\ \frac{ {3}^{2n + 5 + 9} }{ {3}^{1 + 16} } = {3}^{3} \\ \frac{ {3}^{2n + 14} }{ {3}^{17} } = {3}^{3} \\ {3}^{2n + 14 - 17} = {3}^{3} \\ {3}^{2n - 3} = {3}^{3} \\ 2n - 3 = 3 \\ 2n = 3 + 3 \\ 2n = 6 \\ n = \frac{6}{2} \\ n = 3$
