To solve the equation given in the image:

\[
x^{x^{x^2 + 2}} = 4
\]

Let's follow these steps:

### 1. Simplify the Exponent
First, define the exponent as:
\[
y = x^{x^2 + 2}
\]

So, the equation becomes:
\[
x^y = 4
\]

### 2. Solve for \( y \)
We know:
\[
x^{x^2 + 2} = y
\]

This equation should satisfy:
\[
x^y = 4
\]

Taking the logarithm on both sides to solve for \( y \):

\[
y \cdot \log(x) = \log(4)
\]

So:
\[
y = \frac{\log(4)}{\log(x)}
\]

Now substitute \( y = x^{x^2 + 2} \):

\[
x^{x^2 + 2} = \frac{\log(4)}{\log(x)}
\]

### 3. Check for Particular Values of \( x \)
Let's check some potential values for \( x \):

#### Case \( x = 2 \):

If \( x = 2 \):
\[
y = 2^{(2^2 + 2)} = 2^{(4 + 2)} = 2^6 = 64
\]

Substitute into the equation \( x^y = 4 \):
\[
2^{64} \neq 4 \quad \text{(this does not satisfy the equation)}
\]

#### Case \( x = \sqrt{2} \):

If \( x = \sqrt{2} \):
\[
y = \left(\sqrt{2}\right)^{\left((\sqrt{2})^2 + 2\right)} = \left(\sqrt{2}\right)^{(2 + 2)} = \left(\sqrt{2}\right)^4 = 4
\]

Substitute into the equation \( x^y = 4 \):
\[
\left(\sqrt{2}\right)^4 = 4
\]

This indeed satisfies the equation.

### Conclusion
The solution to the equation \( x^{x^{x^2 + 2}} = 4 \) is \( x = \sqrt{2} \).
