The Degree of the polynomial is 3 
 
        
             
        
        
        
Step-by-step explanation:
Step 1:
A .    5 with an exponent of 3 times 5 with an exponent of -4
=  =
  =  =
=  = 1/5
 = 1/5
B .   (1/4) with an exponent of 3 times (1/4) with an exponent of 2
 =  
  
C. Same as above
D.  
Step 2 :
 All the above expressions have a value between 1 and 2
 
        
             
        
        
        
I would think it would be r
        
                    
             
        
        
        
There are 1000 millimetres in a litre, so 1800 ml is 1.8 litres. 3-1.8 is 1.2.
