(1): "^-4" was replaced by "^(-4)".

Step  1  :

 1.1     4 = 22

(4)^-4 = (2²)^(-4) = (2)^(-8)

Equation at the end of step  1  :

Step  2  :

 2.1     4 = 22

(4)⁸ = (2²)⁸ = 2¹⁶

Equation at the end of step  2  :

Step  3  :

                   1
 Divide  216  by  ——
                  28

Multiplying exponents :

 3.1    2¹⁶  multiplied by  2⁸   = 2^{(16 + 8)} = 2²⁴

Final result :

  224
