we have the expression


-27\sqrt[\square]{3}+3\sqrt[\square]{27}

Remember that


27=3^3

substitute in the original expression


-27\sqrt[\square]{3}+3\sqrt[\square]{3^3}

simplify


\begin{gathered} -27\sqrt[\square]{3}+3\cdot3\sqrt[\square]{3^{}} \\ -27\sqrt[\square]{3}+9\sqrt[\square]{3^{}} \\ -18\sqrt[\square]{3} \end{gathered}
