Thread: 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:

That'll explain why I couldn't do it. Thank you
