Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

 (1): "y1"   was replaced by   "y^1". 

Step  1  :

             e 
 Simplify   ———
            156

Equation at the end of step  1  :

           e 
  (((61 • ———) • a) • y157) • a5700
          156

Step  2  :

Equation at the end of step  2  :

  61eay157 
  ———————— • a5700
    156   

Step  3  :

Multiplying exponential expressions :

 3.1    a¹ multiplied by a⁵⁷⁰⁰ = a^{(1 + 5700)} = a⁵⁷⁰¹

Final result :
