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): "8.9" was replaced by "(89/10)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  89
  —— • ((2)(-6)•(5)(-6))
  10

Step  2  :

            89
 Simplify   ——
            10

Equation at the end of step  2  :

  89
  —— • ((2)(-6)•(5)(-6))
  10

Step  3  :

Multiplying exponents :

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

Multiplying exponents :

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

Final result :

     89                                    
  ——————— = 8.90000 • 10-6
