(1): "^-2" was replaced by "^(-2)".

Step  1  :

 1.1     6 = 2•3

(6)² = (2•3)² = 2² • 3²

Equation at the end of step  1  :

  (9-2) • (22•32)

Step  2  :

 2.1     9 = 32

(9)^-2 = (3²)^(-2) = (3)^(-4)

Equation at the end of step  2  :

  (3)(-4) • (22•32)

Step  3  :

Dividing exponents :

 3.1    3²   divided by   3⁴   = 3^{(2 - 4)} = 3^(-2) = ¹/_3²

Final result :

  4           
  — = 0.44444
