Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-3" was replaced by "^(-3)".

(2): "3.56" was replaced by "(356/100)".

Step  1  :

 1.1     10 = 2•5

(10)^-3 = (2•5)^(-3) = (2)^(-3) • (5)^(-3)

Equation at the end of step  1  :

  356
  ——— • ((2)(-3)•(5)(-3))
  100

Step  2  :

            89
 Simplify   ——
            25

Equation at the end of step  2  :

  89
  —— • ((2)(-3)•(5)(-3))
  25

Step  3  :

Multiplying exponents :

 3.1    5²  multiplied by  5³   = 5^{(2 + 3)} = 5⁵

Final result :

     89             
  ——————— = 0.00356 
  (55•23)
