OG12 98

98. On a scale that measures the intensity of a certain
phenomenon, a reading of n + 1 corresponds to an
intensity that is 10 times the intensity corresponding
to a reading of n. On that scale, the intensity
corresponding to a reading of 8 is how many times
as great as the intensity corresponding to a reading
of 3 ?

(A) 5
(B) 50
(C) 105
(D) 510
(E) 810 – 310

OG的解释如下：

Since 8 can be obtained from 3 by “adding 1” fi ve
times, the intensity reading is greater by a factor
of (10)(10)(10)(10)(10) = 105.
Th e correct answer is C.

问题：
1、a reading of n + 1 corresponds to an
intensity that is 10 times the intensity corresponding
to a reading of n. 这句话怎么我都整不明白~~
2、就是OG的解释也不明白，但是估计是因为我连题目都看不明白~~~~

首先lz你的表述有问题，幸好我og在手边查了原题??以后k的n次方要最好表述成k^n
所以题目是
(A) 5
(B) 50
(C) 10^5
(D) 5^10
(E) 8^10 – 3^10

题目的意思是说：如果定义n＋1为n的10倍的话，8是3的多少倍。
这里的话所有数字都不能按原来理解了，因为8＝3＋1＋1＋1＋1＋1，所以是10的5次方

楼上的给了很详细的解释,那我就帮你分析一下你为身么没看懂,我觉得LZ没看懂这道题是因为英语把你饶了, 理解这道题的关键在于词组CORRESPOND TO--相对应, 看看这个词组出现了几次, 而且以动词和后置定语两种型式出现在题中,再加上从句,所以你就瞢了,所以有好多这样的题本不难, 就是英语的憋脚让你摸不着头了, 多练练就好了, GOOD LUCK!
