![y^2\sqrt[8]{8}](https://tex.z-dn.net/?f=y%5E2%5Csqrt%5B8%5D%7B8%7D)
Step-by-step explanation:
![\sqrt[8]{8*y*y*y*y*y*y*y*y*y*y*y*y*y*y*y*y}](https://tex.z-dn.net/?f=%5Csqrt%5B8%5D%7B8%2Ay%2Ay%2Ay%2Ay%2Ay%2Ay%2Ay%2Ay%2Ay%2Ay%2Ay%2Ay%2Ay%2Ay%2Ay%2Ay%7D)
Since there are eight y's in two groups we can take them out which turns into
![y^2\sqrt[8]{8}](https://tex.z-dn.net/?f=y%5E2%5Csqrt%5B8%5D%7B8%7D)

Answer:
-37
Step-by-step explanation:
for the first equation to equal 4 the x must equal -6. 
because something plus 7 had to equal 4. and we know that -3 + 7 equals 4. Now, -6 ÷ 2 equals -3 and that gives us the right answer.
So now plug -6 into the new problem so now it is 
5 × (-6) - 7 so according the PEMDAS, we do 5 × -6 first which is -30. and -30 - 7 equals -37!!
hope this helps :)
 
        
             
        
        
        
Answer:
AU(B n C)= (1,3,5,7,9,6)
Step-by-step explanation:
BnC= (6)
AU(Bn C)= (1,3,5,7,9)U(6)
A U(B n C)= (1,3,5,7,9,6)
 
        
             
        
        
        
Answer:
<-7,-3>
Step-by-step explanation:
To write RS in component form we need to know how far to move over horizontally and then how many to move vertically. 
Since horizontal movement is the x values, we subtract the x values of R and S first. 
0 - 7 = -7
Since vertical movement is in the y values we subtract those next. 
5 - 8 = -3 
So written in component form we have <-7,-3>
