Module 8: Lesson 2

 

Self-Check 6

 

“Check Your Understanding” questions  7.a., 7.d., 22, and 23 on pages 525 and 526 of the textbook

7.  
   1. 
      
      n ≤ −5 since n must be greater than zero, so the answer is n = 6.
      
   4. 
      
      This is now the same question as 7.a., and the solution will be the same, n = 6.

22.  
    1. A possible method for the solution may look as follows.
       
       
        
       
    2. A possible method for the solution may look as follows.
       
       
        
       
    3. A possible method for the solution may look as follows.
       
       
        
       
    4. A possible method for the solution may look as follows.
       
       
        
       
23. A possible explanation looks as follows.
    
    
     
    
    
    In order for the two highlighted values to be equal, this could also be written as The denominators would need to be the same, so 0! must be equal to 1.
