(1): "^-3" was replaced by "^(-3)".

Step  1  :

 1.1     9 = 32

(9)¹² = (3²)¹² = 3²⁴

Equation at the end of step  1  :

  (9-3) • 324

Step  2  :

 2.1     9 = 32

(9)^-3 = (3²)^(-3) = (3)^(-6)

Equation at the end of step  2  :

  (3)(-6) • 324

Step  3  :

Dividing exponents :

 3.1    3²⁴   divided by   3⁶   = 3^{(24 - 6)} = 3¹⁸

Final result :

  318
