I see an abundance of powers with base 5 ....
(5^m)(5^3)(5^(-2))/5^(-5) =5^12
5^(m+3+(-2)-(-5)) = 5^12
5^(m+6) = 5^12
m+6 = 12
m = 6
btw, avoid using × as a multiplication symbol online.
Use either brackets like I did, or use *
e.g. 5*6=30
(5^m)(5^3)(5^(-2))/5^(-5) =5^12
5^(m+3+(-2)-(-5)) = 5^12
5^(m+6) = 5^12
m+6 = 12
m = 6
