Answer
9/2
Work Step by Step
Because of order of operations, we first consider what is within the parenthesis: ($6^{2}$-$3^{3}$) Once within the parenthesis, we know that we first consider exponents and then subtract. Thus, it follows:
($6^{2}$-$3^{3}$)=36-27=9
We use this back in the initial expression to find:
9$\div$2=9/2
=4.5
