It is obvious that the radicals with negative sign tends to be less than those that are positive. So from there you already know a basic order. Now to be sure, you can use a calculator or just solve by squaring the whole number to find the radical form. 
        
             
        
        
        
Answer:
- 2
Step-by-step explanation:
The composition of inverse functions gives x
g(x) and  (x) are inverse functions, then
 (x) are inverse functions, then
 (g(x)) = x , thus
 (g(x)) = x , thus
 (g(- 2)) = - 2
 (g(- 2)) = - 2
 
        
             
        
        
        
22+2/2=23
22 is whole number
one plus sign
and 2/2 is the fraction
4 digits are 2
