I see the image contains a mathematical expression. The equation involves square roots and rational functions, and the key part of it is:

\[
\sqrt{\frac{x^2 + 2 + \frac{1}{x^2}}{x^2 + 2 - \frac{1}{x^2}}} = 3
\]

The goal seems to be solving for \( x \). Let's go step-by-step to solve this equation.

### Step-by-Step Solution:

1. **Square both sides** to remove the square root:
   \[
   \frac{x^2 + 2 + \frac{1}{x^2}}{x^2 + 2 - \frac{1}{x^2}} = 9
   \]

2. **Multiply both sides** by the denominator on the left to clear the fraction:
   \[
   x^2 + 2 + \frac{1}{x^2} = 9 \left( x^2 + 2 - \frac{1}{x^2} \right)
   \]

3. **Distribute the 9** on the right-hand side:
   \[
   x^2 + 2 + \frac{1}{x^2} = 9x^2 + 18 - 9 \cdot \frac{1}{x^2}
   \]

4. **Combine like terms**: Move all terms involving \( x^2 \) and \( \frac{1}{x^2} \) to one side of the equation:
   \[
   x^2 + 9 \cdot \frac{1}{x^2} - 9x^2 - \frac{1}{x^2} = 16
   \]

   Simplify:
   \[
   -8x^2 + 10 \cdot \frac{1}{x^2} = 16
   \]

5. To simplify the equation further, multiply everything by \( x^2 \) to eliminate the fractions.
