Question 34

The square root of 5329 is:

Solution

$$ \sqrt{5329} = 73$$

or, if we divide the number into 2 parts 53 and 29, we can say that the unit place of the number will be either 7 or 3.

so if we check the nearest square of a number which is less than 53 is 49 i.e the tenth's place will be 7. And as we know that 752 =5625 so it will be 73.

So option D is correct.
