(1): "^-9" was replaced by "^(-9)".

Step  1  :

 1.1     10 = 2•5

(10)^-9 = (2•5)^(-9) = (2)^(-9) • (5)^(-9)

Equation at the end of step  1  :

  2512 • ((2)(-9)•(5)(-9))

Step  2  :

Dividing exponents :

 2.1    2⁴   divided by   2⁹   = 2^{(4 - 9)} = 2^(-5) = ¹/_2⁵

Final result :

    157                                    
  ——————— = 2.51200 • 10-6
