    Determining a null sequence

    I'm trying to see if (5n^5) / (n^3) is null.

    I know I need to use the combination rules to work it down to a basic null sequence, like {1/n} etc.

    I don't know which rule to apply and at what stage

    That is impossible to do because it is not true:
    \left(\frac{5n^5}{n^3}\right)=5n^2
