Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-8" was replaced by "^(-8)".

(2): ".006" was replaced by "(006/1000)".

Step  1  :

             3 
 Simplify   ———
            500

Equation at the end of step  1  :

            3 
  (70-8) • ———
           500

Step  2  :

 2.1     70 = 2•5•7

(70)^-8 = (2•5•7)^(-8) = (2)^(-8) • (5)^(-8) • (7)^(-8)

Equation at the end of step  2  :

                               3 
  ((2)(-8)•(5)(-8)•(7)(-8)) • ———
                              500

Step  3  :

Multiplying exponents :

 3.1    2⁸  multiplied by  2²   = 2^{(8 + 2)} = 2¹⁰

Multiplying exponents :

 3.2    5⁸  multiplied by  5³   = 5^{(8 + 3)} = 5¹¹

Final result :

        3                                        
  ———————————— = 1.04080 • 10-17
