Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-9" was replaced by "^(-9)".

(2): "5.2216" was replaced by "(52216/10000)".

Step  1  :

 1.1     10 = 2•5

(10)^-9 = (2•5)^(-9) = (2)^(-9) • (5)^(-9)

Equation at the end of step  1  :

  52216
  ————— • ((2)(-9)•(5)(-9))
  10000

Step  2  :

            6527
 Simplify   ————
            1250

Equation at the end of step  2  :

  6527
  ———— • ((2)(-9)•(5)(-9))
  1250

Step  3  :

Multiplying exponents :

 3.1    2¹  multiplied by  2⁹   = 2^{(1 + 9)} = 2¹⁰

Multiplying exponents :

 3.2    5⁴  multiplied by  5⁹   = 5^{(4 + 9)} = 5¹³

Final result :

     6527                                    
  ————————— = 5.22160 • 10-9 
  (210•513)
