Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-21" was replaced by "^(-21)".

Step  1  :

Equation at the end of step  1  :

  (2 • (2)(-21)) • 10

Step  2  :

Dividing exponents :

 2.1    2¹   divided by   2²¹   = 2^{(1 - 21)} = 2^(-20) = ¹/_2²⁰

Equation at the end of step  2  :

   1 
  ——— • 10
  220

Step  3  :

Dividing exponents :

 3.1    2¹   divided by   2²⁰   = 2^{(1 - 20)} = 2^(-19) = ¹/_2¹⁹

Final result :

   5                                   
  ——— = 9.53674 • 10-6
