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

Steps

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 \(\frac{5\sqrt{2}}{2}\).
