1)  

 Using laws of exponents, simplify in the exponents form

711÷73

7 to the power Answer: 8


SOLUTION 1 :

Soln  :

       =    711÷73              [ am ÷ an  = am-n ]

      =   7(11-3)

     =  78

                 

 



2)  

 Using laws of exponents, simplify in the exponents form

312÷34

3 to the power Answer: 8


SOLUTION 1 :

Soln  :

       =    312÷34              [ am ÷ an  = am-n ]

      =   3(12-4)

     =  38

                 

 



3)  

 Using laws of exponents, simplify in the exponents form

414÷45

4 to the power Answer: 9


SOLUTION 1 :

Soln  :

       =    414÷45              [ am ÷ an  = am-n ]

      =   4(14-5)

     =  49

                 

 



4)  

 Using laws of exponents, simplify in the exponents form

313÷32

3 to the power Answer: 11


SOLUTION 1 :

Soln  :

       =    313÷32              [ am ÷ an  = am-n ]

      =   3(13-2)

     =  311

                 

 



5)  

 Using laws of exponents, simplify in the exponents form

1010÷105

10 to the power Answer: 5


SOLUTION 1 :

Soln  :

       =    1010÷105              [ am ÷ an  = am-n ]

      =   10(10-5)

     =  105

                 

 



6)  

 Using laws of exponents, simplify in the exponents form

314÷37

3 to the power Answer: 7


SOLUTION 1 :

Soln  :

       =    314÷37              [ am ÷ an  = am-n ]

      =   3(14-7)

     =  37

                 

 



7)  

 Using laws of exponents, simplify in the exponents form

615÷69

6 to the power Answer: 6


SOLUTION 1 :

Soln  :

       =    615÷69              [ am ÷ an  = am-n ]

      =   6(15-9)

     =  66

                 

 



8)  

 Using laws of exponents, simplify in the exponents form

211÷27

2 to the power Answer: 4


SOLUTION 1 :

Soln  :

       =    211÷27              [ am ÷ an  = am-n ]

      =   2(11-7)

     =  24

                 

 



9)  

 Using laws of exponents, simplify in the exponents form

310÷33

3 to the power Answer: 7


SOLUTION 1 :

Soln  :

       =    310÷33              [ am ÷ an  = am-n ]

      =   3(10-3)

     =  37

                 

 



10)  

 Using laws of exponents, simplify in the exponents form

715÷79

7 to the power Answer: 6


SOLUTION 1 :

Soln  :
