Answer 2

Answer:

Step-by-step explanation:

[1-i] / [1+i]  =[ 1- i ] [1- i ] / [1+i] [1-i]

               = [1-i]^2 / [1 - i^2 ]

               =[1 - 2i +i^2] /  [1 + 1]

               =[1 - 2i - 1] /2

                 = -2i/2  

                = - i

now  

          [-i] ^[4n+1] = [ -i] ^4n x [-i]

                            =[ [-i]^4 ] ^n  x [-i]

                            = 1^n x [-i]

                             =1x[-i]

                              = -i
