Answer 2

The given data is x = 3+√8.

We have to find the value of

$\frac{ {x}^{2} + 1}{ {x}^{2} }$

So, first step we found the value of

${x}^{2}$

and then We found the value of

${x}^{2} + 1$

Next we substituted all values.

$hence \: \frac{ {x}^{2} + 1 }{ {x}^{2} } = 18 - 12 \sqrt{2} \: or \: \\: 6(3 - 2 \sqrt{2)}$
