Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-13" was replaced by "^(-13)".

(2): "8.9" was replaced by "(89/10)".

Step  1  :

 1.1     10 = 2•5

(10)^-13 = (2•5)^(-13) = (2)^(-13) • (5)^(-13)

Equation at the end of step  1  :

  89
  —— • ((2)(-13)•(5)(-13))
  10

Step  2  :

            89
 Simplify   ——
            10

Equation at the end of step  2  :

  89
  —— • ((2)(-13)•(5)(-13))
  10

Step  3  :

Multiplying exponents :

 3.1    2¹  multiplied by  2¹³   = 2^{(1 + 13)} = 2¹⁴

Multiplying exponents :

 3.2    5¹  multiplied by  5¹³   = 5^{(1 + 13)} = 5¹⁴

Final result :

      89                                      
  ————————— = 8.90000 • 10-13 
  (214•514)
