Porfa ayúdenme se que pido mucho porfa ​

Answer 1

...

${ \sqrt{7 + \sqrt{2 + \sqrt[3]{x} } } }^{2} = {3}^{2} \\ 7 + \sqrt{2 + \sqrt[3]{x} } = 9 \\ \sqrt{2 + \sqrt[3]{x} } = 2 \\ { \sqrt{2 + \sqrt[3]{x} } }^{2} = {2}^{2} \\ 2 + \sqrt[3]{x} = 4 \\ \sqrt[3]{x} = 2 \\ { \sqrt[3]{x} }^{3} = {2}^{3} \\ x = 8$

...

$E = {(8 - 1)}^{2} + {(8 + 1)}^{2} + 1 \\ E = {7}^{2} + {9}^{2} + 1 \\ E = 49 + 81 + 1 \\ E = 131$
