Question

find the least number that should be subtracted from 2240 to make it perfect square​

Answer 1

Step-by-step explanation:

5 is to be subtracted from 4230 to make it a perfect square

4230–5=4225=65*65=65^2

Such problems should be solved using approximations

60^2=3600

70^2=4900

4230 is between 60^2 and 70^2

So we check for 65^2 which is equal to 4225 and is so close to 4230

So 5 should be subtracted from 4230 to make it a perfect square
