13^n-6^n，（n=1,2,3，……）证明：数学归纳法 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 =...
It shows very clearly that Tn is divisible by 3 if n is divisible by 3, and vice versa. It is true that the iconic proof does not allow to substitute arbitrarily large numbers for n and to prove the statement for them because so many dots cannot be drawn; but for smaller numbers the...
运用多项式的除法易将原数因式分解为 2^555+1=(2^5+1)*(2^550-2^545+2^540……-2^5+1)=33*(2^550-2^545+2^540……-2^5+1)得证!
