What is (-2)^2
What is (-2)^3
(-2)(-2) = +4
(-2)(-2)(-2) = -8
To calculate (-2)^2, you raise -2 to the power of 2. This means you multiply -2 by itself. So, (-2)^2 equals (-2) × (-2), which is equal to 4.
To calculate (-2)^3, you raise -2 to the power of 3. This means you multiply -2 by itself three times. So, (-2)^3 equals (-2) × (-2) × (-2), which is equal to -8.
In summary:
(-2)^2 = 4
(-2)^3 = -8
