1)  

 Using laws of exponents, simplify in the exponents form

415÷49

4 to the power Answer: 6


SOLUTION 1 :

Soln  :

       =    415÷49              [ am ÷ an  = am-n ]

      =   4(15-9)

     =  46

                 

 



2)  

 Using laws of exponents, simplify in the exponents form

1010÷108

10 to the power Answer: 2


SOLUTION 1 :

Soln  :

       =    1010÷108              [ am ÷ an  = am-n ]

      =   10(10-8)

     =  102

                 

 



3)  

 Using laws of exponents, simplify in the exponents form

613÷61

6 to the power Answer: 12


SOLUTION 1 :

Soln  :

       =    613÷61              [ am ÷ an  = am-n ]

      =   6(13-1)

     =  612

                 

 



4)  

 Using laws of exponents, simplify in the exponents form

1010÷101

10 to the power Answer: 9


SOLUTION 1 :

Soln  :

       =    1010÷101              [ am ÷ an  = am-n ]

      =   10(10-1)

     =  109

                 

 



5)  

 Using laws of exponents, simplify in the exponents form

815÷83

8 to the power Answer: 12


SOLUTION 1 :

Soln  :

       =    815÷83              [ am ÷ an  = am-n ]

      =   8(15-3)

     =  812

                 

 



6)  

 Using laws of exponents, simplify in the exponents form

513÷53

5 to the power Answer: 10


SOLUTION 1 :

Soln  :

       =    513÷53              [ am ÷ an  = am-n ]

      =   5(13-3)

     =  510

                 

 



7)  

 Using laws of exponents, simplify in the exponents form

511÷56

5 to the power Answer: 5


SOLUTION 1 :

Soln  :

       =    511÷56              [ am ÷ an  = am-n ]

      =   5(11-6)

     =  55

                 

 



8)  

 Using laws of exponents, simplify in the exponents form

612÷61

6 to the power Answer: 11


SOLUTION 1 :

Soln  :

       =    612÷61              [ am ÷ an  = am-n ]

      =   6(12-1)

     =  611

                 

 



9)  

 Using laws of exponents, simplify in the exponents form

712÷76

7 to the power Answer: 6


SOLUTION 1 :

Soln  :

       =    712÷76              [ am ÷ an  = am-n ]

      =   7(12-6)

     =  76

                 

 



10)  

 Using laws of exponents, simplify in the exponents form

714÷77

7 to the power Answer: 7


SOLUTION 1 :

Soln  :

       =    714÷77              [ am ÷ an  = am-n ]

      =   7(14-7)

     =  77
