Reformatting the input :

Changes made to your input should not affect the solution:

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

Step  1  :

 1.1     4 = 22

(4)^-2 = (2²)^(-2) = (2)^(-4)

Equation at the end of step  1  :

    (410) 
  {———————}5
   (2)(-4)

Step  2  :

 2.1     4 = 22

(4)¹⁰ = (2²)¹⁰ = 2²⁰

Equation at the end of step  2  :

     220  
  {———————}5
   (2)(-4)

Step  3  :

                   1
 Divide  220  by  ——
                  24

Multiplying exponents :

 3.1    2²⁰  multiplied by  2⁴   = 2^{(20 + 4)} = 2²⁴

Equation at the end of step  3  :

  224^5

Step  4  :

Final result :

  2120
