Step  1  :

             9
 Simplify   ——
            25

Equation at the end of step  1  :

            9
  (10-2) • ——
           25

Step  2  :

 2.1     10 = 2•5

(10)^-2 = (2•5)^(-2) = (2)^(-2) • (5)^(-2)

Equation at the end of step  2  :

                       9
  ((2)(-2)•(5)(-2)) • ——
                      25

Step  3  :

Multiplying exponents :

 3.1    5²  multiplied by  5²   = 5^{(2 + 2)} = 5⁴

Final result :

    9
