So the ultimate goal is to get to 1/5, aka 5^(-1)

First option:
(5^5)/(1) * (5^7)/(1) *(1)/(5^(13))= (5^(12))/(5^(13))=5^(-1)= (1)/(5)

Second option:
5^5*5^7*5^(-13)=5^(-1)= (1)/(5)

Third option:
(5^(12))/(5^(13))=5^(-1)= (1)/(5)

Fourth option:
(5^5*5^7)/(5^(13)) = (5^(12))/(5^(13))=5^(-1)= (1)/(5)


To summarize, all the options are correct.
