$<b>Answer:$

Given : x = 5

$\bold{x {}^{2} + \frac{1}{x} {}^{2} } \\ \\ \bold{ (5) {}^{2} + \frac{1}{5 {}^{2} }} \\ \\ \bold{25 + \frac{1}{25} }\\ \\ \bold{\frac{625 + 1}{25} }\\ \\ \bold{\frac{626}{25} } \\ \\ \bold{25 \frac{1}{25}}$

Thanks for the question!

Answer 2

$<b>Whenever you solve such questions then, begin by simply substituting the values in the given terms. In this case, the term is x^2 + 1/x^2<b>$
We are given with the value of x i.e. 5

So,
${x}^{2} + \frac{ 1}{ {x}^{2} } \\ {5}^{2} + \frac{1}{ {5}^{2} } \\ 25 + \frac{1}{25} \\ \frac{625 + 1}{25} \\ \frac{626}{25} \\ 25 \frac{1}{25}$
