问题如下:
Paul bought a fund and the return each year is shown below:
The fund's geometric mean will be:
选项:
A.8.2%.
B.1.48%.
C.3.2%.
解释:
A is correct. [(1 + 0.045) × (1 – 0.01) × (1 + 0.201) × (1 + 0.16) × (1 + 0.03)](1/5) – 1 = 8.2%.
老师您好,您回答别的同学“开五次根号的计算器按法是算出前五项乘积等于1.4845后按“yx”,“(”,"1/5,“)”,“=”,可以得到1.0822”
想请问下您“yx”是怎么按的?是第五行Yx吗?数字9的 上面,
能否麻烦您详细写一下“yx”和“1/5”应该如何按出来呢? 1/5是怎么按出来的呢?之前按一直都是1除以5
