The given expression is


54(.)/(.)2*3-x^2

where x=3

the dot in the expression means multiplication

substitute into the expression above we have


\begin{gathered} 54(.)/(.)2*3-3^2 \\ \end{gathered}

Applying BODMAS


27*3-3^2
\begin{gathered} 81-3^2 \\ 81-9 \\ 72 \end{gathered}

Therefore the value of the expression is 72
