Sig figs when problem only gives you "n" values

So when a problem for example asks you to find the amount of energy it takes to move an electron from n=1 to n=3, and those are the only two numbers you are given in the problem, how many dig figs do I use?
Should I use only 1?
Or
Should I use however many are given to me in planks constant or rydbergs constant?

Yes, you should use as many sig figs as are in the constants you use.
