摘要
讨论了与广义Euler函数φ2(n)有关的两个方程φ2(x-φ2(x))=2与φ2(φ2(x-φ2(x)))=2的可解性,利用初等的方法给出了方程φ2(x-φ2(x))=2所有的5个整数解,方程φ2(φ2(x-φ2(x)))=2所有的26个整数解.
The solvabilities of two equations φ2(x-φ2(x))=2 and φ2(φ2(x-φ2(x)))=2 on generalized Euler function φ2(n)were discussed.The equation φ2(x-φ2(x))=2 has 5 solutions and the equation φ2(φ2(x-φ2(x)))=2 has 26 solutions,which were given based on elementary methods.
