Confusing log

$\displaystyle 1/2\log9t^2 = \log\left[(9t^2)^{1/2}\right] = \log3t$



It's just not right... well obviously it is. But... what the heck

I'm pretty sure this is the reason behind most of my errors too!

Ha The answer to life and all of its ills. You know I get this overwhelming sense of satisfaction when I have my coffee in the morning. That's probably not good. Or it's so good it's bad. There's probably a mathematical formula behind it.

I think it must be $\displaystyle \begin{align*} \log{ \left| 3\,t \right| } \end{align*}$...
