1. The problem is to simplify the expression $(–6 – –8)3$. 2. First, simplify inside the parentheses: $–6 – –8$ means $–6 + 8$ because subtracting a negative is the same as adding. 3. Calculate $–6 + 8 = 2$. 4. Now multiply the result by 3: $2 \times 3$. 5. Calculate $2 \times 3 = 6$. 6. Therefore, the simplified value of the expression is $6$.
