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

Step  1  :

 1.1     4 = 22

(4)^-1 = (2²)^(-1) = (2)^(-2)

Equation at the end of step  1  :

  (23) • (2)(-2)

Step  2  :

Equation at the end of step  2  :

  23 • (2)(-2)

Step  3  :

Dividing exponents :

 3.1    2³   divided by   2²   = 2^{(3 - 2)} = 2¹ = 2

Final result :

  2
