I believe your question was:
%28-4a%5E-1%2Ab%5E2%2Ac%5E4%29%2F%282b%5E7c%29
step 1 - reduce the front numbers to get
-2a%5E-1%2Ab%5E2%2Ac%5E4%29%2F%28b%5E7c%29
step 2 - combine your variables using the division rule. WHen you divide like bases, subtract the exponents.
-2a%5E-1%2Ab%5E-5%2Ac%5E3%29
step 3- change all exponents into positives if needed as
-2%2Ac%5E3%2F%28a%2Ab%5E5%29
