(-2)to the 8th power = (-2) (-2) (-2) (-2)(-2)(-2)(-2)(-2) =258

the answer to this would be 256.

Step-by-step explanation:

before explaining this,

- negative x negative = positive

- positive x positive = positive

- negative x positive = negative

- positive x negative = negative

this would be because -2 x -2 it equals 4. then, we multiply 4 x -2 and we get -8, then we multiply -8 x -2 and we get 16, then we keep doing the same thing until we get the answer/ used all the -2's.

1. -2 x -2 = 4

2. 4 x -2 = -8

3. -8 x -2 = 16

4. 16 x -2 = -32

5. -32 x -2 = 64

6. 64 x -2 = -128

7. -128 x -2 = 256
