Respuesta :

It is neither.

The list of perfect squares is {1, 4, 9, 16, 25, 36, 49, 64, ...} and you can see that 55 is not listed. 

The list of perfect cubes is {1, 8, 27, 64, ...} and 55 isn't listed here either

-------------------------------------------------------

Note: To compute the list of perfect squares, you square the set {1,2,3,...}
So 
1^2 = 1
2^2 = 4
3^2 = 9
etc etc

For the perfect cubes, we cube each value from {1,2,3...}
1^3 = 1
2^3 = 8
3^3 = 27
etc etc

Answer:

Neither.

Step-by-step explanation:

We are asked to classify 55.

Let us take square root of 55 to determine whether 55 is a perfect square or not.

[tex]\sqrt{55}[/tex]

[tex]\sqrt{55}=7.41619848\approx 7.42[/tex]

Since 7.42 is not an integer, therefore, 55 is not a perfect square.

Let us take cube root of 55 to determine whether 55 is a perfect cube or not.

[tex]\sqrt[3]{55}[/tex]

[tex]\sqrt[3]{55}=3.802952460\approx 3.80[/tex]

Since 3.80 is not an integer, therefore, 55 is not a perfect cube.

Therefore, 55 is neither perfect square nor perfect cube.
