(1): "^-8" was replaced by "^(-8)".

Step  1  :

 1.1     10 = 2•5

(10)^-8 = (2•5)^(-8) = (2)^(-8) • (5)^(-8)

Equation at the end of step  1  :

  135 • ((2)(-8)•(5)(-8))

Step  2  :

Dividing exponents :

 2.1    5¹   divided by   5⁸   = 5^{(1 - 8)} = 5^(-7) = ¹/_5⁷

Final result :

     27                                    
  ——————— = 1.35000 • 10-6
