Rationalize the expression \(\frac{5}{\sqrt{2}}\).

Step 1 ：Multiply the numerator and the denominator by the conjugate of the denominator, which in this case is \(\sqrt{2}\).

Step 2 ：This gives us \(\frac{5 \cdot \sqrt{2}}{\sqrt{2} \cdot \sqrt{2}}\).

Step 3 ：Simplify the denominator \(\sqrt{2} \cdot \sqrt{2}\) to 2.

Step 4 ：So the expression becomes \(\frac{5\sqrt{2}}{2}\).
