Answer:

23x10000 • (x - 500)

Step-by-step explanation:

Step  1  :

1.1     10 = 2•5

(10)4 = (2•5)4 = 24 • 54

(2x -  (103)) • (4 • (x(2^4•5^4)))

(2x -  (103)) • 22x10000

3.1     10 = 2•5

(10)3 = (2•5)3 = 23 • 53

5.1     Pull out like factors :

  2x - 1000  =   2 • (x - 500)

multiplied by  22   = 2(1 + 2) = 23        23x10000 • (x
