纠正了L2x3kxp≡0(mod3k+1),k∈Z,k≥0,p为任意正整数的错误,然后证明了Lucas数Ln的标准分解式中素因数5指数为0,最后证明了Ln 的标准分解式中素因数7的指数由n的标准分解式中2和7的指数决定。
In this paper, we first correct a mistake in reference [10];then we prove that the index of 5 in Ln is 0;at last, we prove that index of 7 in Ln can be determined by the indexes of 2 and 7 in the standard fac-torization of n.
