  1. a)
    4^10 . 8^15
    = (2^2)^10 . (2^3)^15
    = 2^20 . 2^45
    = 2^65
    b)
    4^15 . 5^30
    = (2^2)^15 . 5^30
    = 2^30 . 5^30
    = 10^30
    c)
    27^16 : 9^10
    = (3^3)^16 : (3^2)^10
    = 3^48 : 3^20
    = 3^28

  2. a ) 4^10 . 8^15 = ( 2^2 )^10 . ( 2^3 )^15 = 2^20 . 2^45 = 2^65
    b ) 4^15 . 5^30 = ( 2^2 )^15 . 5^30 = 2^30 . 5^30 = ( 2 . 5 )^30 = 10^30
    c ) 27^16 : 9^10 = ( 3^3 )^16 : ( 3^2 )^10 = 3^48 : 3^20 = 3^28 .
