 Here is a proof by example that the given method is incorrect:
 
-Assume that the method described in the standard is correct. Let a
-complex number X = 0+I. Let an integer n = -1. Then
+Assume that the method described in the standard is correct.
 
-X**n = 1/i = -i
+Let a complex number X = i and let an integer n = -1.
 
-argument(X) = pi/2 and n is negative.  So, according to G.1.1(55),
-argument(X**n) = (pi/2)/|-1| = pi/2,
+Then X**n = 1/i = -i, argument(X) = pi/2 and n is negative.
+
+So, according to G.1.1(55), argument(X**n) = (pi/2)/|-1| = pi/2,
 but argument(X**n) = argument(-i) = -pi/2
 
 Obviously, pi/2 is not equal to -pi/2 (even as an angle); i.e. a
