首先,a的个位数是7,40^3=64000,30^3=27000,所以40>a>30, a=37

第二步属于穷举出来的,而且是在很小的空间里碰运气。如果a^3的结果是98974793499622030620040256,现求a,阁下又该如何处之?

首先a小于40大于30,1~9的立方个位数是3的只有7,所以a=37 验算37³=50653

小学生才能这么算,学过无理数就不敢这么乱蒙了😂

我小学的时候曾经用过这个思路来解题,然后老师认定我是靠猜的,不算数。然后以后都不学数学了。

50653~51*1000 = (27~64)*10 & 个位为7,得37

第二步不对 50653-343=50310 去一个零,找5031的个位

个位数是7,不可能是大于100的数,然后大于30小于40,瞪眼37

不是教育数学思维,而是筛选高灵感学生

小学压轴题,大学复平面填空题。这题有三个解,怎么才找出来一个?🤪

37啊,多简单。32的三次方,都知道把,32K,32768。40的三次方,64000。这范围就定下来了。

这恐怕算不上什么压轴题吧?请问考了什么知识点?
