The answer is A. The Associative Property, followed by the Associative Property. 
It's because they want you to group stuff, not simplify them.
 
        
                    
             
        
        
        
Answer:
 64q^6r^8s^4
Step-by-step explanation:
 (-8q^3r^4s^2)^2
= (-8)^2 q^(3*2) r^(4*2) s^(2*2)
= 64q^6r^8s^4
 
        
             
        
        
        
Y = <span>b^x
when x = 1
y = b^1
y  = b
Therefore, the value of b is the same as the value of y when x =1
From the graph,
When x = 1, y = 0.5
Therefore, b = 0.5
To confirm this
From the graph,
When x = -1, y = 2
Since </span>y = b^x<span>
2 = </span>b^-1
2 = 1/b
2b = 1
b = 0.5
When x = -2, y = 4
Since y = b^x
4 = b^-2
4 = 1/(b^2)
b^2 = 1/4
b = √(1/4)
b = 1/2
b = 0.5
Therefore, it is conformed that b = 0.5
