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.
There is a formula to calculate even perfect numbers, 2p-1(2p - 1) where p is a prime number. When p = 7 then 26(27 - 1) = 64 x 127 = 8128 So 8128 is the 4th perfect number. (The other three occur when p = 2, 3 and 5)
The sum of the 1st perfect number and 2nd perfect number is. . . 34!
If by 'perfect number' you mean 'perfect SQUARE', then yes. 49 is an odd number and a perfect square.
A perfect number is a number that is the sum of all its proper factors (that is all its factors excluding itself). The next perfect number after 28 is 496
Try it out! For example, you can use a calculator to calculate the number's square root. If you get a whole number - no decimals - then the number is a perfect square.

Then the number is called a "perfect square".Then the number is called a "perfect square".Then the number is called a "perfect square".Then the number is called a "perfect square".
If by 'perfect number' you mean 'perfect SQUARE', then yes. 49 is an odd number and a perfect square.
The largest 3-digit number - not itself a perfect square - is 999. Calculate its square root, round the answer down, then square the answer again.
496 is the third perfect number and 8128 is the fourth perfect number.
There is not a number that is a perfect square and perfect cube between 1 and 25.There is not a number that is a perfect square and perfect cube between 1 and 25.There is not a number that is a perfect square and perfect cube between 1 and 25.There is not a number that is a perfect square and perfect cube between 1 and 25.
Yes it is. 6 is the first perfect number, 28 is the second perfect number.
A perfect number is a number that is the sum of all its proper factors (that is all its factors excluding itself). The next perfect number after 28 is 496
75 is not a Perfect number.
