​$$\sqrt{\frac{\sqrt{211600} + \sqrt{400}}{48000}}$$​equals:

Correct option is B

Given:

​$$\sqrt{\frac{\sqrt{211600} + \sqrt{400}}{48000}}$$​​

Solution:

= $$\sqrt{\frac{\sqrt{211600} + \sqrt{400}}{48000}}$$​​

= $$\sqrt{\frac{460 + 20}{48000}}$$​​

= $$\sqrt{\frac{480}{48000}}$$​​

= $$\sqrt{\frac{1}{100}}$$​​

​$$= \frac{1}{10}$$​​
