Answer 1

Ответ:

$\displaystyle \frac{u+8}{u^{\frac{2}{3}}-2\sqrt[3]{u}+4}-\frac{u-8}{\sqrt[3]{u^2}+2u^{\frac{1}{3}}+4}=\\\\\\=\frac{(u^{\frac{1}{3}}+2)(u^{\frac{2}{3}}-2u^{\frac{1}{3}}+4)}{u^{\frac{2}{3}}-2u^{\frac{1}{3}}+4}-\frac{(u^{\frac{1}{3}}-2)(u^{\frac{2}{3}}+2u^{\frac{1}{3}}+4)}{u^{\frac{2}{3}}+2u^{\frac{1}{3}}+4}=\\\\\\=(u^{\frac{1}{3}}+2)-(u^{\frac{1}{3}}-2)=2+2=4$
