Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-4" was replaced by "^(-4)".

(2): ".39" was replaced by "(39/100)".

Step  1  :

             39
 Simplify   ———
            100

Equation at the end of step  1  :

            39
  (10-4) • ———
           100

Step  2  :

 2.1     10 = 2•5

(10)^-4 = (2•5)^(-4) = (2)^(-4) • (5)^(-4)

Equation at the end of step  2  :

                       39
  ((2)(-4)•(5)(-4)) • ———
                      100

Step  3  :

Multiplying exponents :

 3.1    2⁴  multiplied by  2²   = 2^{(4 + 2)} = 2⁶

Multiplying exponents :

 3.2    5⁴  multiplied by  5²   = 5^{(4 + 2)} = 5⁶

Final result :

     39             
  ——————— = 0.00004 
  (26•56)
