Answer:
A
Step-by-step explanation:


Remember that  x^(b-c)
x^(b-c)
Using that  =3^(1/2x-1/2)=3^((x-1)/2)
=3^(1/2x-1/2)=3^((x-1)/2)

So we can say:  , because the bases are the same
, because the bases are the same
We can multiply both sides of the equation by 2. We get x-1=2, and x=3. Which is A.
 
        
             
        
        
        
can be simplified as 5-9+7=-4+7=3
