(1): "^-4" was replaced by "^(-4)".

Step  1  :

 1.1     10 = 2•5

(10)^-4 = (2•5)^(-4) = (2)^(-4) • (5)^(-4)

Equation at the end of step  1  :

  (9 • ((2)(-4)•(5)(-4)))2

Step  2  :

Equation at the end of step  2  :

     9   
 (———————)2
  (24•54)

Step  3  :

 3.1     9 = 32

(9)² = (3²)² = 3⁴

Final result :

     34                                    
  ——————— = 8.10000 • 10-7
