Examples From Chapter 6 Squares and Square Roots
| Ex. 1 Find the least number that should be added to 252 to get a perfect square. Find the square root of the perfect square thus obtained. Soln: Here we see, 152 < 252 Therefore, the next perfect square is 162 = 256 Hence, the number to be added is 162 – 252 = 256 – 252 = 4 Hence, the perfect square so obtained is 252 + 4 = 256 Hence, √256 = 16. Ex. 2 Solve: (n+1)2 - n2 = ? Soln: (n+1)2 – n2 = (n2 + 2n + 1) – n2 = 2n + 1 |
