# Math Help - n^3, n^4, divisibility

1. ## n^3, n^4, divisibility

hello. I would like to ask for help..
How do I handle this exercise?

Specify the all positive integers $d$, for which it is true to say: For any positive integer $n$, if $n^{4}$ is divisible by $d$, then the number $n^{3}$ is divisible by $d$.

2. ## Re: n^3, n^4, divisibility

hint: what happens if some fourth power of a prime divides d?
