Question

Решить
$\frac{(a^{2}-b^{2})*(\sqrt[3]{a}-\sqrt[3]{b})} {\sqrt[3]{a^{4}}+\sqrt[3]{ab^{3}}-\sqrt[3]{a^{3}b}-\sqrt[3]{b^{4}}}$

Answer 1

$\frac{(a^2-b^2)(a^{\frac{1}{3}}-b^{\frac{1}{3}})}{\sqrt[3]{a}(a+b)-\sqrt[3]{b}(a+b)} =\frac{(a-b)(a+b)(a^{\frac{1}{3}}-b^{\frac{1}{3}})}{(a+b)(a^{\frac{1}{3}}-b^{\frac{1}{3}})} =a-b$
