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): "8.45" was replaced by "(845/100)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  845
  ——— • ((2)(-4)•(5)(-4))
  100

Step  2  :

            169
 Simplify   ———
            20 

Equation at the end of step  2  :

  169
  ——— • ((2)(-4)•(5)(-4))
  20 

Step  3  :

Multiplying exponents :

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

Multiplying exponents :

 3.2    5¹  multiplied by  5⁴   = 5^{(1 + 4)} = 5⁵

Final result :

    169             
  ——————— = 0.00085 
  (26•55)
