Answer
The parentheses are included as \[8-2\cdot \left( 3-4 \right)\].
Work Step by Step
Insert the parentheses as given below to obtain the required result:
\[8-2\cdot \left( 3-4 \right)\]
Now, evaluating the above expression using order of operations as:
\[\begin{align}
& 8-2\cdot \left( 3-4 \right)=8-2\cdot \left( -1 \right) \\
& =8+2 \\
& =10
\end{align}\]
Hence, the parentheses are included as \[8-2\cdot \left( 3-4 \right)\].
