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): "7.85" was replaced by "(785/100)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  785
  ——— • ((2)(-6)•(5)(-6))
  100

Step  2  :

            157
 Simplify   ———
            20 

Equation at the end of step  2  :

  157
  ——— • ((2)(-6)•(5)(-6))
  20 

Step  3  :

Multiplying exponents :

 3.1    2²  multiplied by  2⁶   = 2^{(2 + 6)} = 2⁸

Multiplying exponents :

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

Final result :

    157                                    
  ——————— = 7.85000 • 10-6 
  (28•57)
