Question

what should be added and subtracted from 8888 to get a square number ?

Answer 1

Answer:

The square root of 8888 is 94.27, so the next perfect square is 95^2 or 9025 and therefore the smallest number needing to be added is 137. The closest perfect square is 94^2, or 8784, but that would require the number to be added to be negative, -52.
