Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-12" was replaced by "^(-12)".

(2): "4.042" was replaced by "(4042/1000)".

Step  1  :

 1.1     10 = 2•5

(10)^-12 = (2•5)^(-12) = (2)^(-12) • (5)^(-12)

Equation at the end of step  1  :

  4042
  ———— • ((2)(-12)•(5)(-12))
  1000

Step  2  :

            2021
 Simplify   ————
            500 

Equation at the end of step  2  :

  2021
  ———— • ((2)(-12)•(5)(-12))
  500 

Step  3  :

Multiplying exponents :

 3.1    2²  multiplied by  2¹²   = 2^{(2 + 12)} = 2¹⁴

Multiplying exponents :

 3.2    5³  multiplied by  5¹²   = 5^{(3 + 12)} = 5¹⁵

Final result :

     2021                                     
  ————————— = 4.04200 • 10-12 
  (214•515)
