Log5 (x^2) - log5 (x) = log5 (3) + log5 (4), which is:
The solution
Translate the equation first
log5 (x^2/x) = log5 (3*4),
x^2/x = 12
x^2 = 12x
x^2 - 12x = 0
x (x - 12) = 0
x = 0, 12, while, x = 0

We have the following expression:
2log5x = log54
Rewriting we have:
2log5x = 0.861353116
log5x = 0.861353116 / 2
log5x = 0.430676558
We clear the value of x:
5 ^ (log5x) = 5 ^ (0.430676558)
x = 5 ^ (0.430676558)
x = 2
Answer:
the solution to 2log5x = log54 is:
x = 2
