Question

For how many different digits n is the two-digit number 6n divisible by n? (The expression 6n should be interpreted as a two-digit integer with tens digit 6 and units digit n, not as 6 times n.)

Answers

  2. Answer:
    6 values n
    Step-By-Step Explanation:
    If n  =1        then    6n    =  61    
    n  =2                           =  62    
    n = 3                          =   63    
    n = 4                          =   64    
    n = 5                         =    65    
    n = 6                         =    66    
    These are the only ones that work [ 67/7 , 68/8, 69/9 and 60/0 are not integers  (the last is undefined)]
    So…..6 values of  n
