Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-18" was replaced by "^(-18)".

(2): "3.162" was replaced by "(3162/1000)".

Step  1  :

 1.1     10 = 2•5

(10)^-18 = (2•5)^(-18) = (2)^(-18) • (5)^(-18)

Equation at the end of step  1  :

  3162
  ———— • ((2)(-18)•(5)(-18))
  1000

Step  2  :

            1581
 Simplify   ————
            500 

Equation at the end of step  2  :

  1581
  ———— • ((2)(-18)•(5)(-18))
  500 

Step  3  :

Multiplying exponents :

 3.1    2²  multiplied by  2¹⁸   = 2^{(2 + 18)} = 2²⁰

Multiplying exponents :

 3.2    5³  multiplied by  5¹⁸   = 5^{(3 + 18)} = 5²¹

Final result :

     1581                                     
  ————————— = 3.16200 • 10-18 
  (220•521)
