(1): "^-10" was replaced by "^(-10)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  42 • ((2)(-10)•(5)(-10))

Step  2  :

Dividing exponents :

 2.1    2¹   divided by   2¹⁰   = 2^{(1 - 10)} = 2^(-9) = ¹/_2⁹

Final result :

     21                                     
  ———————— = 4.20000 • 10-9
