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): "1.05" was replaced by "(105/100)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  105
  ——— • ((2)(-20)•(5)(-20))
  100

Step  2  :

            21
 Simplify   ——
            20

Equation at the end of step  2  :

  21
  —— • ((2)(-20)•(5)(-20))
  20

Step  3  :

Multiplying exponents :

 3.1    2²  multiplied by  2²⁰   = 2^{(2 + 20)} = 2²²

Multiplying exponents :

 3.2    5¹  multiplied by  5²⁰   = 5^{(1 + 20)} = 5²¹

Final result :

      21                                      
  ————————— = 1.05000 • 10-20 
  (222•521)
