Question 759371: find x for the following equation:
log[base5](5/x)= 3 + log[base5](x)
I know the answer is x=.2 but I don't understand how that is the answer on the online tutorials I'm working on.

log[base5](5/x)= 3 + log[base5](x)
log[base5](5/x) - log[base5](x) = 3
log[base5]((5/x)/(x)) = 3
log[base5](5/x^2) = 3
5/x^2 = 5^3
1/x^2 = 5^2
1/x^2 = 25
x^2 = 1/25
x = 1/5
x = .2
