Solution - Raising to a power

Step  1  :

Equation at the end of step  1  :

  (1(55^2))     
  ————————— -  5
    (250)      
 Step  2  :
 2.1     55 = 5•11

(55)² = (5•11)² = 5² • 11²

Equation at the end of step  2  :

  (1(5^2•11^2))     
  ————————————— -  5
        1          
 Step  3  :
            1
 Simplify   —
            1
