Question

Simplify
√49
-----
√2

Answer 1

First take the square root of 49 to get 7


\[\Large \frac{\sqrt{49}}{\sqrt{2}}\]


\[\Large \frac{7}{\sqrt{2}}\]

Answer 2

Now multiply both top and bottom by \(\large \sqrt{2}\) to get this


\[\Large \frac{7}{\sqrt{2}}\]


\[\Large \frac{7\sqrt{2}}{\sqrt{2}*\sqrt{2}}\]


\[\Large \frac{7\sqrt{2}}{\sqrt{2*2}}\]


\[\Large \frac{7\sqrt{2}}{\sqrt{4}}\]


\[\Large \frac{7\sqrt{2}}{2}\]
