solve the log: 2logx-log(2x-10)-1=0
Solution
2logx-log(2x-10)-1=0
Use the log property : a*logx = logx^a
logx^2 - log(2x -10) =1
use the log property: logA - logB = Log(A/B)
So, log(x^2/(2x -10) =1
x^2/(2x-10) = 10^1
x^2 = 10(2x -10)
x^2 -20x +100 =0
x^2 - 10x -10x +100 =0
x(x-10) -10(x-10) =0
(x-10)^2 =0
x = 10 (solution)
