First take the square root of 49 to get 7 $\Large \frac{\sqrt{49}}{\sqrt{2}}$ $\Large \frac{7}{\sqrt{2}}$

Now multiply both top and bottom by $$\large \sqrt{2}$$ to get this $\Large \frac{7}{\sqrt{2}}$ $\Large \frac{7\sqrt{2}}{\sqrt{2}*\sqrt{2}}$ $\Large \frac{7\sqrt{2}}{\sqrt{2*2}}$ $\Large \frac{7\sqrt{2}}{\sqrt{4}}$ $\Large \frac{7\sqrt{2}}{2}$
