Just use indices method

I dont think u can minus the power just like that. Unless it is divide that you can minus the powers.
The more plausible answer would be factoring the 7^503 out.. but I still can't evaluate. Unless I think I'm missing some information.

I see because I thought the indices method would work
Is it 505/503 which could be the answer?
