   2^5

c) 2^3 . 5^3 =

   (2.5)^3

  10^3

d) ( 32∶ 8)^5=

    (4)^5

e) (3^5)^3=

   3^(5.3)

   3^15

f) ( 7 ^5 ) ^ 2 =

   7^(5.2)

   7^10

g) (1/3)^4 ∶ (1/3)^2 =

    (1/3) ^(4 - 2)

    (1/3)^2

h) (1 /2)^ 6 . (1/2 )^4 . (1/2)^0 =

   (1/2)^(6 + 4 + 0)

  (1/2)^10

i) ) ( 2/5 )^14 ∶ ( 2 /5)^9 =

    (2/5)^^(14 - 9)

    (2/5) ^5
