Step  1  :

Equation at the end of step  1  :

   (39)
  {————}-2
    35 

Step  2  :

Equation at the end of step  2  :

   39
  {——}-2
   35

Step  3  :

            39
 Simplify   ——
            35

Raising to a Power :

 3.1    3⁹   divided by   3⁵   = 3^{(9 - 5)} = 3⁴

Equation at the end of step  3  :

  81-2

Step  4  :

 4.1     81 = 34

(81)^-2 = (3⁴)^(-2) = (3)^(-8)

Final result :

   1           
  —— = 0.00015
