<font face="Times New Roman" size="+2">

Let *[tex \Large u\ =\ 3^w], then


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ u^2\ +\ 6u\ -\ 27\ =\ 0]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (u\ +\ 9)(u\ -\ 3)\ =\ 0]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ u\ =\ -9\ \Right\ 3^w\ =\ -9] No real solution.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ u\ =\ 3\ \Right\ 3^w\ =\ 3\ \Right\ w\ =\ 1]
