Which of the following has a value that is greater than \(25\)?
Indicate all such values.
A. \(\sqrt{525}\)
B. \(10 \sqrt{6}\)
C. \(\sqrt{625}\)
D. \(2 \sqrt{169}\)
E. \(10 \sqrt{7}\)
Kudos for the right answer and explanation

Here,
We can easily calculate option A, C and D first,
Because, \(25^2 = 625\) and \(13^2 = 169\) , from the information only option D is possible.
As for option B and E, we need to take out the sq-root
A. \(\sqrt{525}\)
We know,\( 25^2 = 625\)
and 525 < 625 , this cannot be possible
B. \(10 \sqrt{6}\)
= 10 * 2.4 = 24, this is out
C. \(\sqrt{625}\)
\(25^2 = 625\), so this option is out
D. \(2 \sqrt{169}\)
= 2 * 13 = 26, this is possible.
E. \(10 \sqrt{7}\)
= 10 * 2.6 = 26, this is an option
