Question

Find the least number which must be added to 6203 to obtain a perfect square also find the square root of the number so obtained​

Answer 1

6203

lies between 4900 (70)² and 6400 (80)²

so for this we will check 75² = 5625

so it is greater than 75²

let's take 78² = 6084

so it is also greater than 78 so it must be 79² = 6241

so 6241 is greater than 6203

so 6241 - 6203 = 38

so 38 must be added to form a perfect square

and it is square of 79

hope it helps
