We know that 512=2^9, which implies that (-2)^9=-512 (since 9 is odd). Thus -2 is one of the 9th root of -512.
There are 8 (or 4 pairs of) other roots that are excluded because they are complex.
Therefore -2 is the only real 9th root of -512.
The answer would be c ASEM
B is the correct answer,
Here's why!
|x+3|<2
case 1 and case 2 states you need to invert it to see which either is
case 1 would be
|-x-3|<2
-x< 5
x>-5
and on the other case
case 2 would be
x+3<2
x<-1
so this means that
B would be your answer!
x>-5 and x<-1

Answer:
{ 2, 4, 6 }
Step-by-step explanation:
These are the only x values that F and G have in common.
