1/5 can be written as 5^-1
log5+log1/5=log(5x1/5)
=log1
=0
because log of 1 to any base is 0.

Your question sounds like you are hunting for something involving powers. People often use logs to raise a number to a power (like to square it, cube it or raise it to the 5 th power).
To raise a number to the 5th power, calculate it's log, multiply by 5, and calculate the antilog (the 10^x key on a scientific calculator). Your question about "power of 1/5" is a method to take the 5th root of some number.

the power of 1^5 you mean ? is; 1*1*1*1*1. log5 + log 1/5 = log 5,1/5.

logA +logB = log(A*B)

therefore
log5+log1/5 = log{5*(1/5)} = log(1) = 0
