Webusing the ratio test, $\dfrac{a_{n+1}}{a_n} = \dfrac{(n+1)x^{n+1}}{nx^n} = \dfrac{(n+1)x}{n}$.
Let us call the roots c_j for 1\leq j\leq m.
$$f(x) = \sum_{n=1}^\infty n.
Webwhat is the derivative of xn?
Product of exponentials with same base.
Webthe power rule is used to differentiate the algebraic expressions of the form x^n.
If we take the product of two exponentials with the same base, we simply add the exponents:
Webfirst remark that the polynomial x^m+k has simple roots.
For the function f (x) = xn, n should not equal 0, for reasons which will become clear.
Therefore x^n/(x^m+k) rewrites as a sum of simple elements.
