Sqrt (625) = 25;.
Sqrt (196) = 14;.
Sqrt (25) = 5;.
Here sqrt = square root of "<number>";
Hence put those in expression and get the value.

Ans is 5.
@Pooja and @Ajo
Sqrt of 625 is 25 * 25,
Sqrt of 25 is 5 * 5,
Sqrt of 196 os 14 * 14.
Now we will write
25/11 * 14/5 * 11/14then if we cut these we will get 25 will cancel by 5 in 5 as 5 * 5 is 25.
11/11 will be same and that's why it will cut as well as 14 /14 it will also be cut.
So, finally, 5 is left so the real answer is 5.

@All.
When we make square root then it must be done for both numerator and denominator.
