Explicación paso a paso:

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

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

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

$3x=3(\sqrt[3]{\sqrt{2}+1 }-\sqrt[3]{\sqrt{2}-1 })$

$x^{3} +3x+8= -3(\sqrt[3]{\sqrt{2}+1 }-\sqrt[3]{\sqrt{2}-1 }) +3(\sqrt[3]{\sqrt{2}+1 }-\sqrt[3]{\sqrt{2}-1 })+8$

$x^{3}+3x+8=8$
