Homework Statement
52x - 3(5x) = 10
Homework Equations
The Attempt at a Solution
log 52x - log 3(5x) = log 10
2x log 5 - log 3 - x log 5 = log 10
x log 5 = log 10 + log 3
x = (log 10 + log 3)/log 5
putting this in my calculator I get 2.11
by inspection I can tell that the answer will be x = 1. So what am I doing wrong?
