Question

Find the least number which must be subtracted from each to make it a perfect square.

Answer 1

Hence, the square root of 784 is 28. We know that, if we subtract the remainder from the number, we get a perfect square. Here, we get the remainder 31. Therefore 31 must be subtracted from 4000 to get a perfect square.

Answer 2

Answer:

Therefore 1 must be subtracted from 3250 to get a perfect square. Hence, the square root of 3249 is 57. We know that, if we subtract the remainder from the number, we get a perfect square.
