一个2000位数最左边的数码是3.在这个整数中,每两个连续的数码必须能被17或23整除.第2000位数可以是a也可以是b,那么a+b的值是多少?
3后面只能加4
4后面只能加6
6后面可以加8或者9
8后加5,后加1,后加7,后无法加
9后加2,后加3,形成循环
所以循环只能是3469234692...
但末尾可以是34685,也可以是34692
这个整数可以是3469234692.34692
也可以是3469234692.34685
a=2,b=5
a+b=7

如果N是正整数,当3^(8n+3) + 2 被5整除的余数是多少?
8n+3 when divided by 4 gives a remainder of 3.
Since powers of 3 make cycles of 4 i.e.3,9,27,81,..3,..9,..7,..1,..3
so 38n+3 will have 7 at the units place.
when 2 is added we get 9 at the units place.
Thus when divided by 5 we get 4 as remainder.

2517=534=533×5,

∴有34位数.
故选B.

!楼上的是错误的.
下面给出正确的解法:
第一题:
(25)^16 * 2^38
= (5)^32 * 2^32 * 2^6
= (5*2)^32 * 2^6
= 8^2 * 10^32
= 6.4*10^33
第二题:
方法一:2+2B=180 180-A-(180-C)=40
a=40度 B=60度 C=80度
(方法二:首先,2等于2B,所以角B的外角加角B就是3B,平角等于180,角B等于60.
剩下的两个内角的和就是120.
又角1加角3等于360-120=240,角1减角3等于40,求出角1为140,角3为100.
所以A=180-140=40,C=180-100=80.
即a=40度 B=60度 C=80度)
第三题:设第一个盒子中有X块糖果
x+16=(176-x-16)m+31
x=(160-x)m+15
x=160m-xm+15
x+mx=160m+15
x=(160m+15)/(1+m)
m>1
那么当m=4时 x最少
x=160*4+15/4+1
x=655/5
x=131块

我们再考虑30000-50000 后面有6个数字可以选择:

1个两位数是它数字之和的7倍.如果数字颠倒,新的两位数是它和的N倍,求N
答案是4
可以设这个数为10X+y
易得10X+Y=7(X+Y)
求10Y+X=N(X+Y)
上下两式一加得N=4

一个两位数的个位与十位数字的和为12
且十为数是个位的2倍.求这个两位数.
设十位数为a,个位数为b
显然 a+b=12
a=2b
所以a=8 b=4
所以为84

译文:
一个两位数是它的各个数位上数字之和的4倍.如果把它的个位数字和十位数字交换,它会增加到21,求这个两位数.
解法:
设这个两位数的个位和十位分别为y,x,即这个数是10x+y
10x+y=4(x+y)
21=10y+x
解得:x=1,y=2
这个两位数是12
