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

Step  1  :

 1.1     75 = 3•52

(75)^-1 = (3•5²)^(-1) = (3)^(-1) • (5)^(-2)

Equation at the end of step  1  :

  10 • ((3)(-1)•(5)(-2))

Step  2  :

Dividing exponents :

 2.1    5¹   divided by   5²   = 5^{(1 - 2)} = 5^(-1) = ¹/_5¹ = ¹/₅

Final result :

   2           
  —— = 0.13333
