Find the value of  $$\sqrt{625}+\sqrt{\frac{{625}}{100}}+\sqrt{\frac{{625}}{10000}}+\sqrt{\frac{{625}}{1000000}}$$​​

Correct option is B

Solution: 

​$$=\sqrt{625}+\sqrt{\frac{{625}}{100}}+\sqrt{\frac{{625}}{10000}}+\sqrt{\frac{{625}}{1000000}} \\ \ \\ =25+{\frac{{25}}{10}}+{\frac{{25}}{100}}+{\frac{{25}}{1000}} \\ \ \\ = 25 + 2.5 + 0.25+0.025 \\ \ \\ = \bf 27.775$$​​
