Solution - Simplification or other simple results

Step  1  :

             y 
 Simplify   ———
            100

Equation at the end of step  1  :

              y 
  (((x100) • ———) • x) • y100
             100
 Step  2  :

Equation at the end of step  2  :

   x100y 
  (————— • x) • y100
    100 
 Step  3  :

Multiplying exponential expressions :

 3.1    y¹ multiplied by y¹⁰⁰ = y^{(1 + 100)} = y¹⁰¹

Final result :

  x101y101
