You have the following expressions given in the problem shown in the figure attached:
2ab(∛192ab^2)-5(∛81a^4b^5)
When you simplify by applying the radical properties, you obtain:
4x2ab∛(3ab^2)-5x3√(a^4b^5)
Therefore, you have:
8ab∛(3ab^2)-15√(3a^4b^5)
8ab∛(3ab^2)-15√(3a^4b^5)
8ab∛(3ab^2)-15ab√(3ab^2)
-7ab(∛(3ab^2))
The answer is: -7ab(∛(3ab^2))
