Answer 1

Answer:

hope this helps you :)

Step-by-step explanation:

(1 + 1/i)^4 = [ (1 + 1/i)^2 ]^2

                 = [ 1 + (1/i)^2 + 2(1/i) ]^2

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

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

                   = (2/i)^2

                  = 4/i2

               = 4/-1

               = -4

now ,

4 (1+i)^4= 4x(-4)

           = -16
