Answer 2

Heya dear user !!!

Here is your answer,

=================================

343 = 7 × 7 × 7 = 7³ ( It's a perfect cube )

516 = 2 × 2 × 3 × 43 ( it's not a perfect cube )

729 = 9 × 9 × 9 = 9³ ( it's a perfect cube )

8000 = 20 × 20 × 20 = 20³ ( it's a perfect cube)

=================================

Hence, 343 , 729 and 8000 are perfect cubes but 516 is not a perfect cube.

=================================

Hope it helps.
