${ \bigg(\frac{2}{5} \bigg)}^{ - 4} \times { \bigg( \frac{5}{4} \bigg) }^{ - 4} \\ \\ { \bigg(\frac{5}{2} \bigg)}^{ 4} \times { \bigg(\frac{4}{5} \bigg)}^{ 4} \\ \\ \frac{ \cancel{{5}^{4}} }{ {2}^{4} } \times \frac{ {4}^{4} }{ \cancel{ {5}^{4}} } \\ \\ \frac{ {2}^{ \cancel8} }{ \cancel{{2}^{4} }} \\ \\ {2}^{4}$
