Answer:

32

Step-by-step explanation:

Given the expression:


5-2\mleft[\mleft(-3\mright)^2+\mleft(-1-2\mright)^3\mright]-9

We use the order of operations BODMAS.

First, we evaluate the expressions inside the brackets.


=5-2\mleft[\mleft(-3\mright)^2+\mleft(-3\mright)^3\mright]-9

Next, we evaluate the Powers/Order(O).


\begin{gathered} =5-2\mleft[9+\mleft(-27\mright)^{}\mright]-9 \\ =5-2\lbrack9-27\rbrack-9 \\ =5-2(-18)-9 \\ =5+36-9 \\ =32 \end{gathered}
