Find the least number that must be added...

Find the least number that must be added to 1300 so as to get a perfect square. Also find the square root of the perfect square.

Text Solution

Verified by Experts

If we try to calculate the square root of `1300`, then we get a remainder `4`.
So, if we subtract `4` from `1300` then we get a perfect square.
So, perfect square = `1300- 4= 1296`
The square root of `1296= 36`

It means, `37^2 gt1300 gt 36^2`.
So, `37^2 = 1369`
As `1369` is a perfect square, if we add `69` to `1300`, then we get a perfect square.
