Chapter 0, Problem 1.93(choose chapter or problem)
Let: = re' 11 be a nonzero complex number and /1 a negative integer (11 = -I. -2 ... . ). Then define: 1 .: 11 by means of the equation: 1 ,..,, = (:- 1 ) l:'m where /11 = -11. By showing that the /11 values of (: 1 :'m)- 1 and (:- 1 ) 1,.m arc the same. verify that :1:' 11 = (: 1,.."')- 1 (Compare with Exercise 7. Sec. 9.)
