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)10^5
(D)5^10
(E)8^10-3^10
Ans:C

不太懂題目的意思!希望幫忙解答..謝謝!

在衡量某現象的密度的尺規,n+1代表的密度是n的密度的十倍,
尺規上讀起來是8的密度, 是讀起來是3的密度的幾倍
8-3=5 →相差1,密度差10倍,所以是10*10*10*10*10=10^5
