刚在网上看到一个数学题,求解题过程!
谢谢。问10个箱子分别装几个水果刚在网上看到一个数学题,要求能够用这10个箱子随机拼出1~1000中的任意数(不能拆开箱子),16,8,489?答案是1:1000个水果用10个箱子来装,64。我想问下的是做题的过程是怎么样的,4,128,256,32
提问者采纳
是一定要的 .12,8.15也都有了
16没办法出来 就再来 16 然后就想一下
就可以找出规律了 答案是1.13,32,256一题要慢慢考虑的 ,128.7 就都有了
.10,这样5.,2,64,4. 9..6, 8 又要来.14, 这样3就有了
,16,4 还拼不出就再来个4

2的n次方是最多素数的倍数,当用1与尽可能多的2n次搭配是可组合成最多数。

运输途中破裂一些。最后结算时发现,亏了60%,未破裂的西瓜卖完后,利润率为40%;破裂的西瓜只能降价出售,总利润为32%,破裂了多少个西瓜某商店购进西瓜1000个

破了x个.4x-0,则好的1000-x个所以40%(1000-x)-60%x=1000×32%400-0.6x=320x=80答
