From the problem :

In multiplying expressions with the same bases, the exponent will be added accordingly.
For example :

the exponent of a are m and n, and the product will be a raised to the sum of m and n.
Applying this to the problem, we have :

The answer is d. 6^-1
 
        
             
        
        
        
Out of 120 students in exam, 2/3 of them passed. How many students passed?
now,
no of students passed = 2/3×120
 = 0.66×120
 =80...
therefore <em>8</em><em>0</em><em> </em><em> </em><em>students</em><em> </em><em>were</em><em> </em><em>passed</em><em>.</em><em>.</em><em>.</em><em>.</em>
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
6 times 4 is 24 so the answer is 24
 
        
             
        
        
        
the highest score is obviously going to be 2125 because that is 100%
 
        
             
        
        
        
The answer would be multiplication and subtraction
