Abstract
In this paper we intend to discuss the stability of
\[
\sum\limits^n_{i=1}\sum\limits^m_{j=1}f(p_iq_j)=\sum\limits^n_{i=1}M_1(p_i)\sum\limits^m_{j=1}g(q_j)+\sum\limits^m_{j=1}M_2(q_j)\sum\limits^n_{i=1}h(p_i),
\]
where \(f:I\to \mathbb R\), \(g:I\to \mathbb R\), \(h:I\to \mathbb R\) are unknown mappings; \(M_1:I\to \mathbb R\), \(M_2:I\to \mathbb R\) are fixed multiplicative mappings both different from identity mapping; \((p_1,\dots,p_n)\in \Gamma_n\), \((q_1,\dots,q_m)\in \Gamma_m\) ; \(n\ge 3\), \(m\ge 3\) are fixed integers.
