Question

What would be added to 7912 to make the sum a perfect squre?

Answer 1

Heya !!!





(88)² = 7744




(89)² = 7921





Let X should be added to 7912 to make it 7921.






Therefore,





7912 + X = 7921





X = 7921 - 7912




X = 9.




Hence,




9 is added to 7912 to make it perfect square.
