No, 80 is a not perfect square.

7 Or -8

They are numbers that are NEAR PERFECT. a near perfect number is when its factors (exept the actual number) are added up and ALMOST equal the number ex. 16x1/2x8/4x4/ so its factors are 1,2,4,8 and 16 so add them ( exept the actual number) 1+2+4+8=15 so its NEAR PERFECT and a perfect number is a number that all its factors equal to its number ex. 6-1,2,3,6 are its factors all together-1+2+3=6 those are NEAR PERFECT and PERFECT numbers

The numbers are 55, 56 and 57 OR 54, 56 and 58

No, 3.6 is not a perfect square. A perfect square is defined as a number that has a whole number for a square root. In other words, there's no whole number that, when multiplied by itself, equals 3.6.

56 2,2,2,7 perfect cubes=1,8

For a number to be a perfect square and a perfect cube, it must be a perfect sixth power. Now 36 = 729 is too small and 56 = 15625 is too large, leaving 46 = 4096 as the answer.

No because there is no number that can be multiplied by itself to get 56. Examples of perfect squares: 4*4= 16 8*8= 64 5*5= 25 16, 64, and 25 are all perfect squares because you can multiply one number by it's self to get those numbers.

The question could ask for the perfect cube of 56, which equals 563 = 175616. However, it can also mean to ask whether 56 can be a cube, which could be answered by 56(1/3), which cubed is 56. Since 56(1/3) is an irrational number, it is impossible to construct this perfectly, but one can make arbitrary precise approximations, close to 3.825862365...

Two reasons why 56 doesn't belong: 1). It's the only one on the list that is not a perfect square. 2). It's the only one on the list that is smaller than the previous number.
