Answer 2

$[a]\:\:\:( \frac{ {5}^{6} }{ {5}^{2} } ) \times {3}^{4} \\ \\ {5}^{6 - 2} \times {3}^{4} \\ \\ {5}^{4} \times {3}^{4} \\ \\ {5 \times 3}^{4} \\ \\ {15}^{4} .$

$[b]\:\:\:\frac{ {2}^{8} \times {x}^{2} \times {y}^{3} }{ {8}^{2} \times {x}^{3} \times {y}^{2} } \\ \\ \frac{ {2}^{8} \times {y}^{3 - 2} }{ {2}^{2} \times {2}^{2} \times {2}^{2} \times {x}^{3 - 2} } \\ \\ \frac{ {2}^{8} \times y}{ {2}^{6} \times x } \\ \\ {2}^{8 - 6} y {x}^{ - 1}\\\\{2}^{2}y{x}^{-1} .$
