# Log

**Algebra**Level 4

\[ 2\log_x a + \log_{ax} a + 3\log_b a = 0 \]

For \(a>0 \) and \(b=a^2 x\), solve the equation above.

If the solutions can be expressed as \(a^c\) and \(a^d\), and \(c + d \) can be expressed as \(-\dfrac ef\) for coprime positive integers \(e\) and \(f\), evaluate \(e-f\).
