Homework Statement




The question is attached in the picture.

The Attempt at a Solution



Since V0 = 1,

Thus V1 = \stackrel{1}{2}∏R2 which is a constant.

Then shouldn't Vn be as in the picture?

I think there is a typo in the question.

(\sqrt{R^2 - x^2}) should be (\sqrt{R^2 - x^2})^n

V_1(R) = <br /> \int_{-R}^R V_0 \left(\sqrt{R^2-x^2} \right) \, dx = \int_{-R}^R \; 1 \, dx = 2R,
etc.

There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
