1)  

 Using laws of exponents, simplify in the exponents form

412÷45

4 to the power Answer: 7


SOLUTION 1 :

Soln  :

       =    412÷45              [ am ÷ an  = am-n ]

      =   4(12-5)

     =  47

                 

 



2)  

 Using laws of exponents, simplify in the exponents form

414÷48

4 to the power Answer: 6


SOLUTION 1 :

Soln  :

       =    414÷48              [ am ÷ an  = am-n ]

      =   4(14-8)

     =  46

                 

 



3)  

 Using laws of exponents, simplify in the exponents form

614÷66

6 to the power Answer: 8


SOLUTION 1 :

Soln  :

       =    614÷66              [ am ÷ an  = am-n ]

      =   6(14-6)

     =  68

                 

 



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

1012÷106

10 to the power Answer: 6


SOLUTION 1 :

Soln  :

       =    1012÷106              [ am ÷ an  = am-n ]

      =   10(12-6)

     =  106

                 

 



6)  

 Using laws of exponents, simplify in the exponents form

611÷66

6 to the power Answer: 5


SOLUTION 1 :

Soln  :

       =    611÷66              [ am ÷ an  = am-n ]

      =   6(11-6)

     =  65

                 

 



7)  

 Using laws of exponents, simplify in the exponents form

414÷46

4 to the power Answer: 8


SOLUTION 1 :

Soln  :

       =    414÷46              [ am ÷ an  = am-n ]

      =   4(14-6)

     =  48

                 

 



8)  

 Using laws of exponents, simplify in the exponents form

1012÷107

10 to the power Answer: 5


SOLUTION 1 :

Soln  :

       =    1012÷107              [ am ÷ an  = am-n ]

      =   10(12-7)

     =  105

                 

 



9)  

 Using laws of exponents, simplify in the exponents form

913÷96

9 to the power Answer: 7


SOLUTION 1 :

Soln  :

       =    913÷96              [ am ÷ an  = am-n ]

      =   9(13-6)

     =  97

                 

 



10)
