Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-9" was replaced by "^(-9)".

Step  1  :

 1.1     4 = 22

(4)^-9 = (2²)^(-9) = (2)^(-18)

Equation at the end of step  1  :

Step  2  :

 2.1     4 = 22

(4)⁵ = (2²)⁵ = 2¹⁰

Equation at the end of step  2  :

Step  3  :

                   1 
 Divide  210  by  ———
                  218

Multiplying exponents :

 3.1    2¹⁰  multiplied by  2¹⁸   = 2^{(10 + 18)} = 2²⁸

Final result :

  228
