好像没什么再简便的了吧~
我再问一个哈:
On a scale that measures the intensity of a certian 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?
答案为10的5次方。
请教大家!
万分感谢! |
