since the exponents have common bases of 5, we can think of it like 4-2, since the 5^2 being in the denominator makes it negative, and since n^4 is left unaffected, we are left over with (5^2)(n^4)
I feel like typing words to explain it would make you confused so instead I took an screenshot of step by step on how to do it and the answer to you’re question.
