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

Step  1  :

 1.1     10 = 2•5

(10)^-1 = (2•5)^(-1) = (2)^(-1) • (5)^(-1)

Equation at the end of step  1  :

  4 • ((2)(-1)•(5)(-1))

Step  2  :

Dividing exponents :

 2.1    2²   divided by   2¹   = 2^{(2 - 1)} = 2¹ = 2

Final result :

  2           
  — = 0.40000
