Помогите пожалуйста

Answer 1

$2)\frac{\sqrt[3]{a^{2}*\sqrt[4]{a}} }{\sqrt[6]{a\sqrt{a}}} =\frac{\sqrt[3]{a^{2}*a^{0,25}} }{\sqrt[6]{a*a^{0,5}}}=\frac{\sqrt[3]{a^{2,25}}}{\sqrt[6]{a^{1,5}}}=\sqrt[6]{\frac{a^{4,5} }{a^{1,5}}}=\sqrt[6]{a^{3}}=\boxed{\sqrt{a}}\\\\\\3)\frac{b-\sqrt[3]{b} }{\sqrt[3]{b^{2}}+\sqrt[3]{b}}=\frac{\sqrt[3]{b^{3}}-\sqrt[3]{b}}{\sqrt[3]{b}(\sqrt[3]{b}+1)}=\frac{\sqrt[3]{b}(\sqrt[3]{b}+1)(\sqrt[3]{b}-1)}{\sqrt[3]{b}(\sqrt[3]{b}+1)}=\boxed{\sqrt[3]{b}-1}$
