Abstract : In this paper, we prove the generalized Hyers-Ulam stability results controlled by considering approximately mappings satisfying conditions much weaker than Hyers and Rassias conditions for radical quadratic and radical quartic functional equations in quasi-$\beta$-normed spaces.
Keywords : radical functional equations, generalized Hyers-Ulam stability, quasi-$\beta$-normed spaces
