lia'nu问题如下图：
选项：
A. 
B. 
C. 
解释：
e^(120/112)=1.07? 是不是我把概念搞混了？这难道不是连续复利的rate?
NO.PZ2017092702000093 问题如下 The weekly closing prices of MorCorporation shares are follows:The continuously compounreturn of MorCorporation shares for the perioAugust 1 to August 15 is closest to: A.6.90% B.7.14% C.8.95% A is correct.The continuously compounreturn of asset over a periois equto the naturlog of perios change. In this case: ln(120/112) = 6.90%资产在一段时间内的连续复合回报等于期间变化的自然对数。 在本题中ln(120/112) = 6.90% 这个公式可以一下背后的逻辑吗

In this case: ln(120/112) = 6.90%资产在一段时间内的连续复合回报等于期间变化的自然对数。 在本题中ln(120/112) = 6.90% 可以理解连续复利，但是15天的连续在计算中怎么提现的呢，假如题里问8天时的连续复利收益，除了把120替换成160，还有其他计算区别吗

NO.PZ2017092702000093 7.14% 8.95% A is correct. The continuously compounreturn of asset over a periois equto the naturlog of perios change. In this case: ln(120/112) = 6.90% 资产在一段时间内的连续复合回报等于期间变化的自然对数。 在本题中ln(120/112) = 6.90% 能一下为什么用ln计算么，没太懂
NO.PZ2017092702000093 为什么不能直接用（1+r/m）^m=FV/PV 这样来算呢，这样算出来是答案B。
