Answer 2

$\frac{x\sqrt[3]{x}-1 }{\sqrt[3]{x^{2}}-1 }-\frac{\sqrt[3]{x^{2}}-1 }{\sqrt[3]{x}+1 }=4\\\\\frac{\sqrt[3]{x^{4}}-1 }{\sqrt[3]{x^{2}}-1} -\frac{(\sqrt[3]{x}-1)(\sqrt[3]{x}+1)}{\sqrt[3]{x}+1} =4\\\\\ \frac{(\sqrt[3]{x^{2}} -1)(\sqrt[3]{x^{2}}+1)}{\sqrt[3]{x^{2}}-1 }-\sqrt[3]{x}+1=4\\\\\sqrt[3]{x^{2}} +1-\sqrt[3]{x}+1-4=0\\\\(\sqrt[3]{x})^{2}-\sqrt[3]{x}-2=0\\\\\sqrt[3]{x}=-1-neyd\\\\\sqrt[3]{x}=2-teorema.Vieta\\\\x=8\\\\Otvet:\boxed{8}$
