Question

solve log3x+log9=0

Answer 1

Adding logs is like taking the log of the product. Assuming your equation is
\[\log 3x + \log 9 = 0\] (and not something involving a log base 3!) that is the same as writing \[\log 9*3x = 0\] or \[\log 27x = 0\]Take the anti-log of both sides and solve for \(x\).
