Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-20" was replaced by "^(-20)".

(2): "2.46" was replaced by "(246/100)".

Step  1  :

 1.1     10 = 2•5

(10)^-20 = (2•5)^(-20) = (2)^(-20) • (5)^(-20)

Equation at the end of step  1  :

  246
  ——— • ((2)(-20)•(5)(-20))
  100

Step  2  :

            123
 Simplify   ———
            50 

Equation at the end of step  2  :

  123
  ——— • ((2)(-20)•(5)(-20))
  50 

Step  3  :

Multiplying exponents :

 3.1    2¹  multiplied by  2²⁰   = 2^{(1 + 20)} = 2²¹

Multiplying exponents :

 3.2    5²  multiplied by  5²⁰   = 5^{(2 + 20)} = 5²²

Final result :

     123                                      
  ————————— = 2.46000 • 10-20 
  (221•522)
