Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-6" was replaced by "^(-6)".

(2): ".7" was replaced by "(7/10)".

Step  1  :

             7
 Simplify   ——
            10

Equation at the end of step  1  :

            7
  (10-6) • ——
           10

Step  2  :

 2.1     10 = 2•5

(10)^-6 = (2•5)^(-6) = (2)^(-6) • (5)^(-6)

Equation at the end of step  2  :

                       7
  ((2)(-6)•(5)(-6)) • ——
                      10

Step  3  :

Multiplying exponents :

 3.1    2⁶  multiplied by  2¹   = 2^{(6 + 1)} = 2⁷

Multiplying exponents :

 3.2    5⁶  multiplied by  5¹   = 5^{(6 + 1)} = 5⁷

Final result :

     7                                     
  ——————— = 7.00000 • 10-7
