 \frac{ {9}^{n}  \times  {3}^{2} \times  {3}^{n} -  {27}^{n}   }{ { ({3}^{3}) }^{5} \times   {2}^{3}  }  =  \frac{1}{27}  \\  =  >   \frac{ {3}^{2n + 2 + n}  -  {3}^{3n} }{ {3}^{18} }  =  {3}^{ - 3}  \\  =  >  {3}^{3n + 2}  -  {3}^{3n}  =  {3}^{15}  \\  =  >  {3}^{3n} (9 - 1) =  {3}^{15}  \\  =  >  {3}^{n}  \times 8 =  {3}^{12}  \\  =  > 8 =  {3}^{12 - n}  \\  =  >   {3}^{1.9}  =  {3}^{12 - n}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: (approx) \\  =  > 1.9 = 12 - n \\  =  > n = 12 - 1.9 \\  =  > n = 10.1
