OG(11th) 99

[hungji]

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 the 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) 10^5
(D) 5^10
(E) 8^10-3^10



答案 C 何解?

題目的大意是說, 有一種測量某種現象強度的方法, 當利用這個方法得到的讀數是 n+1 時, 表示該強度為讀數是 n 時的 10 倍, 然後題目要問的是當讀數為 8 時是讀數為 3 時的多少倍? 我想可能是不清楚題意的關係吧.....
10^(8-3) = 10^5 , 答案為 (C)
