The problem asks to rationalize the denominator of the expression:

\[
\frac{5 + \sqrt{2}}{\sqrt{2}}
\]

To rationalize the denominator, we need to eliminate the square root from the denominator. We can achieve this by multiplying both the numerator and denominator by \(\sqrt{2}\), as follows:

\[
\frac{5 + \sqrt{2}}{\sqrt{2}} \times \frac{\sqrt{2}}{\sqrt{2}} = \frac{(5 + \sqrt{2}) \times \sqrt{2}}{(\sqrt{2})^2}
\]

Now, simplify the terms:

1. In the numerator:
\[
(5 + \sqrt{2}) \times \sqrt{2} = 5\sqrt{2} + \sqrt{2} \times \sqrt{2} = 5\sqrt{2} + 2
\]

2. In the denominator:
\[
(\sqrt{2})^2 = 2
\]

Thus, the expression becomes:

\[
\frac{5\sqrt{2} + 2}{2}
\]

This is the rationalized form of the expression.
