7的202次方第十位是5，谁能给讲讲怎么才能作出来

chinwei

这是我用power calculator算出来的，从前数还是从后数，第十位都不是4啊。

7^202
    512630076274403501575926080979023869331140238958341449337556864117721162603788850336944748130558838464360197164374769394529095836840495968219386959099651010197235349880049

这道题什么思路？

这里的链接我看了，问题是为什么要按照0440循环？答案所有的人都说是4，可是我的计算结果却是5啊。

It should be a minor typo, should be 49^100 = (49^2)^50 but it does not matter at all, because its only a power.
