Answer 2

Heya !!

Here's your answer.. ⬇⬇
________________________________

$x + \frac{1}{x} = 8 \\ \\ taking \: \: square \: \: on \: \: both \: \: side ... \\ \\ {(x + \frac{1}{x} )}^{2} = {(8)}^{2} \\ \\ {(x)}^{2} + 2 + \frac{1}{ {(x)}^{2} } = 64 \\ \\ {(x)}^{2} + \frac{1}{ {(x)}^{2} } = 64 - 2 \\ \\ {(x)}^{2} + \frac{1}{ {(x)}^{2} } = 62$
