If \(a\in L\) ends with an even digit, its square will be divisible by 4, while if it ends with an odd digit, the square will be odd. So \(a^{2}=2\) is not possible. Preston:: That’s right. What about \(\sqrt{5}\)? Let’s assume we have \(a=\ldots a_{3}a_...
employs the macrostructural approach to neurological plausibility by considering how the study of cerebral hemisphere asymmetry can contribute to the psychology of word meanings argued here that each hemisphere has its own semantic system and that both are required during on-line comprehension for the ...
1，当n=1时，原式=13^n-6^n=13-6=7，可以被7整除 2，假设，n=m时，原式=13^m-6^m可以被7整除，3，当n=m+1时，原式=13^(m+1)-6^(m+1)=13*13^m-6*6^m =(7+6)*13^m-6*6^m =7*13^m+6*13^m-6*6^m =7*13^m+6(13^m-6^m)因为，7*13^m可以被7整除、...
