Because numbers are infinite, there is an infinite number of answers. e.g. What number should be added to 2 to make a perfect square? 2+2=4 (a perfect square) 2+7=9 (a perfect square) 2+14=16 (a perfect square) 2+23=25 (a perfect square) etc... Did you have a specific number in mind.

Try 25

35, which makes 66 squared.

Hi, do you mean what square number is closest to 4321? 66 squared is 4356 which is 35 from 4321 if that's what you mean? it mean that 35 is least no. whih should be added to 4321 to make it perfect square

144

23 because 97321+23 = 97344 which is a square number and its square root is 312

It is: 64 because the square root of 1089 is 33

The least number is -6710. That gives the sum as 6710 + (-6710) = 0, which is a perfect square.The least positive number is 14.

62

Sqrt of 453664 is 672 and a bit.So next square is 673 squared, ie 452929, so 265 must be added.

12

125: 225 = 152, 289 = 172

(Y2 + Y) added to (Y + 1) will always give a perfect square [of (Y + 1)2].

Here is how you can figure this out. Take the square root of 7581. Round this up. Square the result. This will give you the closest perfect square that is larger than 7581. Calculate the difference.

Lets see... sq root 8888 = 94.27618999514140314737153695235 952 = 9025, 9025 - 8888 = 137 so add 137 assuming you want a perfect square that is an integer.

96 + 4 = 100 96 + 25 = 121 96 + 100 = 196 96 + 529 = 625

sqrt 12345 is about 111.1062 so the next perfect square is 1122= 12544 so you have to add 199

you please answer this question and mail me

sqrt(81180) = 284.9 So the next square is 285. 2852 = 81225 so need to add 45

24 should be added because 68 times 68 = 4624

The least number that can be added to 60 to obtain a perfect cube is 4. Add 4 to get 64 whose cube root is 4

A number is perfect if all it's factors (barring itself) sum to make the original number. In this case, the factors of 28 are 1,2,4,7 and 14. Added up, these equal 28. Thus, 28 is a perfect number.
