Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-2" was replaced by "^(-2)".

(2): "3.5" was replaced by "(35/10)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  35
  —— • ((2)(-2)•(5)(-2))
  10

Step  2  :

            7
 Simplify   —
            2

Equation at the end of step  2  :

  7
  — • ((2)(-2)•(5)(-2))
  2

Step  3  :

Multiplying exponents :

 3.1    2¹  multiplied by  2²   = 2^{(1 + 2)} = 2³

Final result :

   7
