Answer:
[tex]-6m^2n^2[/tex]
Step-by-step explanation:
[tex]\frac{\left(4m^2\right)\left(3n^5\right)}{\left(2m^{-3}\right)\left(-mn\right)^3}[/tex]
[tex]\frac{4m^2\cdot \:3n^5}{2m^{-3}\left(-mn\right)^3}[/tex]
[tex]\frac{12m^2n^5}{2m^{-3}\left(-mn\right)^3}[/tex]
[tex]\frac{12m^2n^5}{-2m^{-3}\left(mn\right)^3}[/tex]
[tex]-\frac{12m^2n^5}{2m^{-3}\left(mn\right)^3}[/tex]
[tex]-6m^2n^2[/tex]
