Changes made to your input should not affect the solution:

(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  :

  120000 • ((2)(-9)•(5)(-9))

Step  2  :

Dividing exponents :

 2.1    2⁶   divided by   2⁹   = 2^{(6 - 9)} = 2^(-3) = ¹/_2³

Dividing exponents :

 2.2    5⁴   divided by   5⁹   = 5^{(4 - 9)} = 5^(-5) = ¹/_5⁵

Final result :

     3              
  ——————— = 0.00012
