Sagot :

From the given picture

Since the power is an odd number, then the negative sign will be in the final answer, then

[tex](-8)^1=-(8)^1=-8[/tex]

It is V

Since any number to the power of 0 is equal to 1 (except 0), then

[tex]8^0=1^{}[/tex]

Then 8^0 = 0 is F

Since the power of the number not include the sign of the number, then there is no change in the sign of the answer

[tex]-8^2=-64[/tex]
