    a )
    2 ^ 3 . 2 ^ 4
    =  2^(3+4)
    = 2^ 7
    = 128
    b)
    5 ^ 3 : 125
    = 5^3 : ( 5 . 5 . 5 )
    = 5^3 : 5^ 3    
    =  125 : 125        hoặc         = 5^(3- 3)
    = 1                                          = 1

  2. a) 2³ . $2^{4}$ 
    = $2^{3 + 4}$ 
    = $2^{7}$ 
    = 128
    b) 5³ : 125
    = 5³ : ( 5 . 5 . 5 )
    = 5³ : 5³
    = 1
