Question

In need of help ASAP!! BRANNIEST TO ANYONE WHO AWNSERS PLEASE

Answer 1

all correct! all can be simplified to 1/5

Answer 2

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.
