2 to the 8th power is 256.
It's the same as doing 2x2x2x2x2x2x2x2=256.
Answer: 1:2
Step-by-step explanation: if she sleeps 8 hours out of 24 hours, 8 goes into 24, 3 times so 1 to 2 ratio because you subtract the time she is awake from the time she is asleep
-4m-24=-8
(add 24 to both sides)
-4m=16
(divide by -4 on both sides)
m=-4
Your answer, in your set notation, is
{-2, 7}
