Substitute -5 for m and 3 for n in the expression and simplify.
[tex]\begin{gathered} (\frac{2m^{-1}n^5}{3m^0n^4})^2=\lbrack\frac{2(-5)^{-1}(3)^5}{3(-5)^0(3)^4}\rbrack^2 \\ =\lbrack-\frac{2}{15}(3)^{5-4}\rbrack^2 \\ =\lbrack-\frac{6}{15}\rbrack^2 \\ =\frac{4}{25} \end{gathered}[/tex]
So value of expression is 4/25.
