问题如下：
The following exhibit shows the annual returns for Fund Y.
The geometric mean return for Fund Y is closest to:
选项：
A.14.9% B.15.6% C.19.5%解释：
A is correct. The geometric mean return for Fund Y is found as follows:
Fund Y= [(1 + 0.195) x (1-0.019) × (1 + 0.197) x (1 + 0.350) x (1 + 0.057)](1/5) -1 = 14.9%.
1、前面的括号里计算出来的值是5.779，然后再进行五分之一次方的计算，得出来的数是1.42，再用1.42减1，得出来的是42%呀？
2、是否能用A*H=G平方来计算？
我公式是对的，但第一次也是算出来括号内的值是5.779 （😣），再次核算后都是2.0023了。但不知道按错了哪个数值。看来只能多按几遍计算器了。
