چکیده
|
In this paper, we prove the generalized hyers-ulamrassias stability of the generalized radical cubic functional equation f (√3 ax^3 + by^3 ) = af(x) + bf(y), where a, b ∈ r+ are fixed positive real numbers, by using direct method in quasi-β-banach spaces. moreover, we use subadditive functions to investigate stability of the generalized radical cubic functional equations in (β, p)-banach spaces.
