Test whether the given numbers are perfect cubes or not.

8000

Given, a number 8000 and need to find out whether it is perfect cube or not.

Now, we have the perfect cube = , where m and n are integers

⇒ 8000 is a perfect cube as it can be expressed as

n × n × n form the product of three equal

integer.

⇒ 8000 = 20 × 20 × 20

Hence, 8000 is a perfect cube.
