To solve the expression −(−2)3, we need to first calculate the inner power and then apply the outer negative sign.
- Step 1: Calculate (−2)3.
Since (−2) is raised to the power of 3, we perform the multiplication: (−2)×(−2)×(−2).
(−2)×(−2)=4.
Continuing, 4×(−2)=−8.
Thus, (−2)3=−8.
- Step 2: Apply the outer negative sign.
We have −(−2)3=−(−8).
According to arithmetic rules, a negative times a negative becomes positive, so −(−8)=8.
Therefore, the solution to the problem is 8, which matches choice number 2.
