(1): "^-5" was replaced by "^(-5)".

Step  1  :

 1.1     9 = 32

(9)³ = (3²)³ = 3⁶

Equation at the end of step  1  :

  (9-5) • 36

Step  2  :

 2.1     9 = 32

(9)^-5 = (3²)^(-5) = (3)^(-10)

Equation at the end of step  2  :

  (3)(-10) • 36

Step  3  :

Dividing exponents :

 3.1    3⁶   divided by   3¹⁰   = 3^{(6 - 10)} = 3^(-4) = ¹/_3⁴

Final result :

   1           
  —— = 0.01235
