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

Step  1  :

 1.1     8 = 23

(8)^-3 = (2³)^(-3) = (2)^(-9)

Equation at the end of step  1  :

  (84) • (2)(-9)

Step  2  :

 2.1     8 = 23

(8)⁴ = (2³)⁴ = 2¹²

Equation at the end of step  2  :

  212 • (2)(-9)

Step  3  :

Dividing exponents :

 3.1    2¹²   divided by   2⁹   = 2^{(12 - 9)} = 2³

Final result :

  8
