I saw a question on internet, tried to solve but I can't:
\begin{equation} 3^x\cdot x^3 = 1 \end{equation}
I get $\ln$ function and made some equalization and I reached that:
\begin{equation} -x\cdot\ln(3) = 3\cdot\ln(x) \end{equation}
I could not continue after that. How does it solve?
Wolfram|Alpha says nearly $x\approx 0.757$.
I searched on Google and on that site but I could not found anything (I guess about the mathematical sign).
