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): ".26" was replaced by "(26/100)".

Step  1  :

            13
 Simplify   ——
            50

Equation at the end of step  1  :

           13
  (10-2) • ——
           50

Step  2  :

 2.1     10 = 2•5

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

Equation at the end of step  2  :

                      13
  ((2)(-2)•(5)(-2)) • ——
                      50

Step  3  :

Multiplying exponents :

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

Multiplying exponents :

 3.2    5²  multiplied by  5²   = 5^{(2 + 2)} = 5⁴

Final result :

   13            
  ———— = 0.00260
