✨Well mate, u have done the correct one.

✨$\bold {Explanation}$

${} = \frac {7 \sqrt{14}}{ \sqrt {343}}$

${} = \frac { \sqrt {7 \times 7 \times 7 \times 2}}{ \sqrt {7 × 7 × 7}}$

${} = \frac { \sqrt {2} \times \sqrt {7 × 7 × 7}} { \sqrt {7 × 7 × 7}}$

${} = \sqrt {2}$

Done.. ✔️

$\huge {Thanks..}$

Answer 2

Answer:

Option(D)

Step-by-step explanation:

$Given:\frac{7\sqrt{14}}{\sqrt{343}}$

$=\frac{7\sqrt{2*7}}{\sqrt{49*7}}$

$=\frac{7*\sqrt{2}*\sqrt{7}}{\sqrt{49}*\sqrt{7}}$

$=\frac{7*\sqrt{2}*\sqrt{7}}{7*\sqrt{7}}$

$=\sqrt{2}$

Hope it helps!
