The expression given is,
[tex]\frac{5^2}{5^{-4}}[/tex][tex]5^2\div5^{-4}[/tex]
Applying Divsion rule of Indices
[tex]\frac{a^m}{a^n}=a^{m-n}[/tex]
Hence,
[tex]5^2\div5^{-4}=5^{2--4}=5^{2+4}=5^6[/tex]
Therefore, the answer is
[tex]5^6[/tex]
Thus, Desa's is correct because the final answer is a positive exponent.
