1)  

 Using laws of exponents, simplify in the exponents form

915÷97

9 to the power Answer: 8


SOLUTION 1 :

Soln  :

       =    915÷97              [ am ÷ an  = am-n ]

      =   9(15-7)

     =  98

                 

 



2)  

 Using laws of exponents, simplify in the exponents form

1014÷104

10 to the power Answer: 10


SOLUTION 1 :

Soln  :

       =    1014÷104              [ am ÷ an  = am-n ]

      =   10(14-4)

     =  1010

                 

 



3)  

 Using laws of exponents, simplify in the exponents form

1014÷109

10 to the power Answer: 5


SOLUTION 1 :

Soln  :

       =    1014÷109              [ am ÷ an  = am-n ]

      =   10(14-9)

     =  105

                 

 



4)  

 Using laws of exponents, simplify in the exponents form

712÷78

7 to the power Answer: 4


SOLUTION 1 :

Soln  :

       =    712÷78              [ am ÷ an  = am-n ]

      =   7(12-8)

     =  74

                 

 



5)  

 Using laws of exponents, simplify in the exponents form

514÷56

5 to the power Answer: 8


SOLUTION 1 :

Soln  :

       =    514÷56              [ am ÷ an  = am-n ]

      =   5(14-6)

     =  58

                 

 



6)  

 Using laws of exponents, simplify in the exponents form

615÷66

6 to the power Answer: 9


SOLUTION 1 :

Soln  :

       =    615÷66              [ am ÷ an  = am-n ]

      =   6(15-6)

     =  69

                 

 



7)  

 Using laws of exponents, simplify in the exponents form

215÷24

2 to the power Answer: 11


SOLUTION 1 :

Soln  :

       =    215÷24              [ am ÷ an  = am-n ]

      =   2(15-4)

     =  211

                 

 



8)  

 Using laws of exponents, simplify in the exponents form

712÷73

7 to the power Answer: 9


SOLUTION 1 :

Soln  :

       =    712÷73              [ am ÷ an  = am-n ]

      =   7(12-3)

     =  79

                 

 



9)  

 Using laws of exponents, simplify in the exponents form

711÷74

7 to the power Answer: 7


SOLUTION 1 :

Soln  :

       =    711÷74              [ am ÷ an  = am-n ]

      =   7(11-4)

     =  77

                 

 



10)  

 Using laws of exponents, simplify in the exponents form

513÷51

5 to the power Answer: 12


SOLUTION 1 :

Soln  :

       =    513÷51              [ am ÷ an  = am-n ]

      =   5(13-1)

     =  512
