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): "4.48" was replaced by "(448/100)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  448
  ——— • ((2)(-4)•(5)(-4))
  100

Step  2  :

            112
 Simplify   ———
            25 

Equation at the end of step  2  :

  112
  ——— • ((2)(-4)•(5)(-4))
  25 

Step  3  :

Multiplying exponents :

 3.1    5²  multiplied by  5⁴   = 5^{(2 + 4)} = 5⁶

Canceling Out :

 3.2      Canceling out  2⁴ as it appears on both sides of the fraction line

Final result :

   7           
  —— = 0.00045 
  56
