On a type of exponential functional equation and its superstability in the sense of Ger

الأصل · EN

In this paper, we deal with a type exponential functional equation as follows f(xy)=f(x)ᵍ⁽ʸ⁾, where f and g are two real valued functions on a commutative semigroup. Our aim of this paper is to proved that the above functional equation in the sense of Ger is superstable.
