对于方程Φ(n)=S(n11),Φ2(n)=S(n11)进行了研究,并得到了这两个方程的所有正整数解,其中Φ( n )为 Euler 函数,Φ2( n )为广义 Euler 函数, S ( n )为 Smarandache函数。%The equations Φ( n)=S( n11 ) and Φ2( n)=S( n11 ) are studied and their positive integer so⁃lutions are found,where Φ( n) is Euler function,Φ2( n) is generalized Euler function,and S( n) is Smaran⁃dache function.
