Homework Statement



Find the MacLaurin series expansion of f(x)=(x^3)/(x+2). Find also the higher derivative f(10)(0)

Homework Equations





The Attempt at a Solution



I'm not sure how to approach this question. The derivative of f(x) becomes larger and larger and I'm not sure how to calculate the higher derivative.

Hint:

\frac{1}{1-x}=1+x+x^2+x^3+...

Can you use this to find the power series of

\frac{1}{x+2}
 
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...
