Expanding the given expression:
(2m^2n - 5mn^2) (3mn^2 - 4m^2n)= 2m^2n 3mn^2 + 2m^2n (-4m^2n) - 5mn^2 3mn^2 - 5mn^2 * (-4m^2n)= 6m^3n^3 - 8m^4n^2 - 15m^2n^4 + 20m^3n^3= 26m^3n^3 - 8m^4n^2 - 15m^2n^4
Therefore, the expanded expression is 26m^3n^3 - 8m^4n^2 - 15m^2n^4.
Expanding the given expression:
(2m^2n - 5mn^2) (3mn^2 - 4m^2n)
= 2m^2n 3mn^2 + 2m^2n (-4m^2n) - 5mn^2 3mn^2 - 5mn^2 * (-4m^2n)
= 6m^3n^3 - 8m^4n^2 - 15m^2n^4 + 20m^3n^3
= 26m^3n^3 - 8m^4n^2 - 15m^2n^4
Therefore, the expanded expression is 26m^3n^3 - 8m^4n^2 - 15m^2n^4.
