Answer 1

Respuesta:

34

Explicación paso a paso:

${x}^{2} + 1 = 6x \\ x + \frac{1}{x} = 6 \\ ( {x + \frac{1}{x}) }^{2} = ( {6})^{2} \\ {x}^{2} + \frac{1}{ {x}^{2} } + 2x. \frac{1}{x} = 36 \\ {x}^{2} + \frac{1}{ {x}^{2} } + 2 = 36 \\ {x}^{2} + \frac{1}{ {x}^{2} } = 36 - 2 = 34 \\ {x}^{2} + \frac{1}{ {x}^{2} } = {x}^{2} + {x}^{ - 2} = 34$
