Answer 2

Given:

A number 7250

To Find:

The least number must be subtracted from 7250 to get a perfect square

Solution:

To find the least number that must be subtracted we will first find the square root of the given number.

So,

The square root of 7250

=√7250

Which is equal to 85.1469

85.1469 can be rounded off and is approximately equal to 85

Now

85² = 7225

It is observed that the perfect square before 7250 is 7225

So,

The number that must be subtracted = 7250-7225

=25

Hence, The least number must be subtracted from 7250 to get a perfect square is 25.
