Question

28.Find the smallest number which when added to 7669 makes the resultant a perfect square.

Answer 1

Answer: 75

Step-by-step explanation:

when we try and find the square root by long division we get remainder as 100,

so if we subtract 100 from 7669, we get 7569 which is the square of 87

then we have 88, the square of 88 is 7744

so we shall add 75 (7744-7669) to 7669 to make it a perfect square
