$\int_{-8}^{8} \frac{x^{5}+x^{3}}{4-x^{2}} d x=$

$\int_{-8}^{8} \frac{x^{5}+x^{3}}{4-x^{2}} d x=$
  1. 16
  2. 0
  3. 8
  4. $-8$

Solution

Let $\quad I=\int_{-8}^{8} \frac{x^{5}+x^{3}}{4-x^{2}} d x$ Let $f(x)=\frac{x^{5}+x^{3}}{4-x^{2}} \Rightarrow f(-x)=\frac{-\left(x^{5}+x^{3}\right)}{4-x^{2}}$ $\therefore \quad \mathrm{f}(-\mathrm{x})=-\mathrm{f}(\mathrm{x}) \Rightarrow \mathrm{I}=0$
