(1): "^-8" was replaced by "^(-8)".

Step  1  :

 1.1     9 = 32

(9)^-8 = (3²)^(-8) = (3)^(-16)

Equation at the end of step  1  :

  (93) • (3)(-16)

Step  2  :

 2.1     9 = 32

(9)³ = (3²)³ = 3⁶

Equation at the end of step  2  :

  36 • (3)(-16)

Step  3  :

Dividing exponents :

 3.1    3⁶   divided by   3¹⁶   = 3^{(6 - 16)} = 3^(-10) = ¹/_3¹⁰

Final result :

   1            
  ——— = 0.00002
