No
Step-by-step explanation:
23.64112 > 23.6404 
Reason : 1/1000 place value in 23.64112  is 1.
1/1000 place value in 23.6404  is 0.
 
        
                    
             
        
        
        
√64 = 8
64÷1000 = 0.0064
8÷1000=0.0008
√0.0064 = 0.0008
        
                    
             
        
        
        
10[(6 + 4) / 2]
10[10/2]
10 * 5
50 <==
        
             
        
        
        
If you would like to solve the equation k / 2 + 9 = 30, you can calculate this using the following steps:
k / 2 + 9 = 30
k / 2 = 30 - 9 
k / 2 = 21     /*2
k = 21 * 2
k = 42
The result is 42.
