The given mathematical expression is:

\[
x + \frac{1}{x} = 0 \quad \text{and} \quad \sqrt{2} \left( \sqrt{x} + \frac{1}{\sqrt{x}} \right)
\]

We are asked to find the value of the expression.

Let's break it down step by step:

1. From \( x + \frac{1}{x} = 0 \), solving for \(x\), we get:

\[
x = -\frac{1}{x}
\]

Multiplying both sides by \(x\), we get:

\[
x^2 = -1
\]

So, \(x = i\), where \(i\) is the imaginary unit.

2. Substituting \(x = i\) into the expression \(\sqrt{2} \left( \sqrt{x} + \frac{1}{\sqrt{x}} \right)\), we first need to calculate \(\sqrt{x}\) and \(\frac{1}{\sqrt{x}}\) for \(x = i\).

   - \(\sqrt{i} = \frac{1}{\sqrt{2}} + i \frac{1}{\sqrt{2}}\)
   - \(\frac{1}{\sqrt{i}} = -\frac{1}{\sqrt{2}} + i \frac{1}{\sqrt{2}}\)

3. Adding them together and multiplying by \(\sqrt{2}\), we can find the final value of the expression.
