Answer:
4
Step-by-step explanation:
AO = OC
3x - 4 = 8
x = 4
 
        
                    
             
        
        
        
Since all of the bases (x) are equal you just add the exponents. 
(The x has an exponent of 1)
3 + -4 + 1 
-1 + 1
0
Since the answer is 0 it is x^0
And any number or variable set to the power of 0 equals 1, therefore...
ANSWER: x^3 • x^-4 • x = 1
Hope this helps!
