${3}^{2}\cdot {9}^{2} \cdot27\cdot {3}^{ - 5} \cdot9\cdot {3}^{ - 4} = \\ {3}^{2}\cdot {3}^{4} \cdot {3}^{3} \cdot {3}^{ - 5} \cdot {3}^{2} \cdot {3}^{ - 4} = \\ {3}^{2}$

${8}^{3}\cdot {4}^{ - 3} \cdot {16}^{3} \cdot {8}^{ - 5} \cdot64\cdot {32}^{2} = \\ {2}^{9}\cdot {2}^{ - 6} \cdot {2}^{12} \cdot {2}^{ - 15} \cdot {2}^{6} \cdot {2}^{10} = \\ {2}^{16}$
