Answer 1

Respuesta:

$E = \sqrt{1 + ( \frac{ {x}^{4} - 1}{2 {x}^{2} } ) {}^{2} } \\ E = \sqrt{1 + \frac{ {x}^{8} + 1 - 2 {x}^{4} }{4 {x}^{4} } } \\ E = \sqrt{ \frac{4 {x}^{4} + {x }^{8} + 1 - 2 {x}^{4} }{4 {x}^{4} } } \\ E = \sqrt{ \frac{ {x}^{8} +2 {x}^{4} + 1 }{4 {x}^{4} } } \\ E = \sqrt{ \frac{( {x}^{4} + 1) {}^{2} }{4 {x}^{4} } } \\ E = \frac{ {x}^{4} + 1 }{2 {x}^{2} }$
