Answer: The expression can be simplified as follows:
(3^{x-1} * 27^x * 9^2) = 3^{x-1 + 2} * 27^x
(3^{2x-4) * 81^x} = 3^{2x-4 + 2x} * 3^{-2x}
Replace in the expression: (3^{x-1 + 2} * 27^x) / (3^{2x-4 + 2x} * 3^{-2x}) = 3^{x-1 + 2 - 2x + 4} * 27^x / 3^4 = 3^3 * 27^x / 81
So the simplified expression is 3^3 * 27^x / 81.
