Uprav výraz \( \frac{x^{3}-x^{2}}{x^{n+1}}-\frac{4 x^{5}+x^{3}}{x^{n+3}}-\frac{4-x}{x^{n}} \) pre \( x \neq 0 \).
\( =\frac{-3 x^{2}-5}{x^{n+1}}=-\frac{3 x^{2}+5}{x^{n+1}} \)
\( =\frac{-3 x^{2}+5}{x^{n}}=-\frac{3 x^{2}-5}{x^{n}} \)
\( =\frac{-3 x^{2}-5}{x^{n}}=-\frac{3 x^{2}+5}{x^{n}} \)
\( =\frac{-3 x^{2}-5}{x^{n-1}}=-\frac{3 x^{2}+5}{x^{n-1}} \)
