Is 500 a perfect cube?

  • 1

No, 500 is not a perfect cube. Its prime factors are 2 × 2 × 5 × 5 × 5. The 2s cannot be grouped into a triplet. So, 500 is not a cube because all factors must occur in threes.

  1. Let’s factorise 500:
    500 = 2² × 5³
    For a number to be a cube, all prime factors must appear in triplets. Here, the factor 2 appears only twice, which cannot make a group of three. Therefore, 500 is not a perfect cube, as it cannot be written as the cube of any integer.
