Burger King(汉堡王)的优惠

in hive-180932 •  5 years ago  (edited)

今天Burger King推出了一个新的优惠，做道数学题获得一个免费的汉堡

自己并不怎么吃Burger King，因为他们家的儿童套餐的玩具实在太丑了！

但是看到解数学题送免费汉堡这个活动，被数学题给吸引到了

所以就下载了他家的APP看看是什么数学题

看了一下题目，看起来很复杂，其实很简单：

ca7f53f8959e2047cb1d9498b1a3584.jpg

第一部分，[5!x5/4!]^1/2, 可以分成[5x5x4!/4!], 得到25, 25的1/2平分就是5
第二部分，(-1)^i, i 是从1到461， 其实就是看是正数还是负数, 461是奇数，所以大括号里面的结果是负数。
结合第一部分和第二部分，大括号里面的结果是-5.
因为外面还有一个负号，所以负的-5等于5. 答案是5

填入答案5获得免费汉堡的优惠券

换了一个手机，发现还是同一道题，Burger King可以考虑一下添加多点习题，做些习题比吃汉堡有趣点

                    哈哈，本来挺爱吃whopper的，自从看来Robert Downey Jr说他因为吃了一顿难吃的Burger King从此把毒都戒了，开始对自己的口味开启了怀疑的模式。

                    现在看到数学题，不怀疑了，再也不吃了……

                      大学时经常吃whopper，有孩子后就没怎么去了，因为勇敢不喜欢他们家的玩具。
