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

Step  1  :

 1.1     4 = 22

(4)³ = (2²)³ = 2⁶

Equation at the end of step  1  :

  (2-2) • 26

Step  2  :

Equation at the end of step  2  :

  (2)(-2) • 26

Step  3  :

Dividing exponents :

 3.1    2⁶   divided by   2²   = 2^{(6 - 2)} = 2⁴

Final result :

  16
