Question
Is 150 a perfect cube?
✓
Answer
Given, number is 150.
Now, prime factorisation of 150
$150=2 \times 3 \times 5 \times 5$
The prime factors of 150 do not appear in group of triples.
Hence, 150 is not a perfect cube.
Now, prime factorisation of 150
$150=2 \times 3 \times 5 \times 5$
| 2 | 150 |
| 5 | 75 |
| 5 | 15 |
| 3 | 3 |
| 1 |
Hence, 150 is not a perfect cube.
