Question

Oberserve as situações apresentadas abaixo e marque V para verdadeiros e F para falso. justifique sua resposta. ( ) (-8)¹=-8( )8⁰=0( )-8²=-64 ( )-8³=-512

Answer 1

From the given picture

$(-8)^1$

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

$(-8)^1=-(8)^1=-8$

It is V

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

$8^0=1^{}$

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

$-8^2=-64$

Then it is V

$-8^3=-(8)^3=-512$

Then it is V
