Step-by-step explanation:

The square of a binomial is a form worthy of memorization.

(a +b)² = a² +2ab +b²

<h3>Application</h3>

Here, you have a binomial with a=x² and b=1/x². Using these values in the pattern, we have ...

$\left(x^2+\dfrac{1}{x^2}\right)^2=(x^2)^2+2(x^2)\dfrac{1}{x^2}+\left(\dfrac{1}{x^2}\right)^2\\\\=\boxed{x^4+2+\dfrac{1}{x^4}}$
