1)  

 Using laws of exponents, simplify in the exponents form

411÷48

4 to the power Answer: 3


SOLUTION 1 :

Soln  :

       =    411÷48              [ am ÷ an  = am-n ]

      =   4(11-8)

     =  43

                 

 



2)  

 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

                 

 



3)  

 Using laws of exponents, simplify in the exponents form

715÷71

7 to the power Answer: 14


SOLUTION 1 :

Soln  :

       =    715÷71              [ am ÷ an  = am-n ]

      =   7(15-1)

     =  714

                 

 



4)  

 Using laws of exponents, simplify in the exponents form

210÷21

2 to the power Answer: 9


SOLUTION 1 :

Soln  :

       =    210÷21              [ am ÷ an  = am-n ]

      =   2(10-1)

     =  29

                 

 



5)  

 Using laws of exponents, simplify in the exponents form

215÷27

2 to the power Answer: 8


SOLUTION 1 :

Soln  :

       =    215÷27              [ am ÷ an  = am-n ]

      =   2(15-7)

     =  28

                 

 



6)  

 Using laws of exponents, simplify in the exponents form

215÷25

2 to the power Answer: 10


SOLUTION 1 :

Soln  :

       =    215÷25              [ am ÷ an  = am-n ]

      =   2(15-5)

     =  210

                 

 



7)  

 Using laws of exponents, simplify in the exponents form

710÷78

7 to the power Answer: 2


SOLUTION 1 :

Soln  :

       =    710÷78              [ am ÷ an  = am-n ]

      =   7(10-8)

     =  72

                 

 



8)  

 Using laws of exponents, simplify in the exponents form

213÷24

2 to the power Answer: 9


SOLUTION 1 :

Soln  :

       =    213÷24              [ am ÷ an  = am-n ]

      =   2(13-4)

     =  29

                 

 



9)  

 Using laws of exponents, simplify in the exponents form

514÷59

5 to the power Answer: 5


SOLUTION 1 :

Soln  :

       =    514÷59              [ am ÷ an  = am-n ]

      =   5(14-9)

     =  55

                 

 



10)  

 Using laws of exponents, simplify in the exponents form

410÷42

4 to the power Answer: 8


SOLUTION 1 :

Soln  :

       =    410÷42              [ am ÷ an  = am-n ]

      =   4(10-2)

     =  48
