Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

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

(2): "2.75" was replaced by "(275/100)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  275
  ——— • ((2)(-3)•(5)(-3))
  100

Step  2  :

            11

Equation at the end of step  2  :

  11
  —— • ((2)(-3)•(5)(-3))
  4 

Step  3  :

Multiplying exponents :

 3.1    2²  multiplied by  2³   = 2^{(2 + 3)} = 2⁵

Final result :
