999 is a perfect cube.
विकल्प
True
False
उत्तर
This statement is False.
Explanation:
| 3 | 999 |
| 3 | 333 |
| 3 | 111 |
| 37 | 37 |
| 1 |
Resolving 999 into prime factors, we get
999 = 3 × 3 × 3 × 37
Grouping the factors in triples of equal factors, we get
999 = (3 × 3 × 3) × 37
Clearly, in grouping, the factor in triples of equal factors, we are left with one factor 37.
Therefore, 999 is not a perfect cube.
