呼呼,怎么也想不明白,求教NN们~~
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?
在一种度量某一现象的强度的标度中,n+1所对应的强度是n所对应强度的十倍。在该标度中,8所对应的强度是3所对应强度的多少倍?
我的理解是:
n+1=10n,
那么8所对应的强度是:7+1=10*7
3所对应的强度是:2+1=10*2
那么比值不就应该是7/2吗?
谢谢大家啦~~~
