i^(9)+i^(10)-3i^(12)=-4

i^(12)+i^(13)+i^(14)+i^(15)

Write the following in the form x+iy: (i) i+i^(2)+i^(3)+i^(4) (ii) i^(4)+i^(8)+i^(12)+i^(16) (iii) i+i^(5)+i^(9)+i^(13) (iv) i^(9)+i^(10)+i^(11)+i^(12) .

If z=(sqrt3-i)/(2) then (i^(101)+z^(101))^(103)=

Show that ((19- 7i)/(9 + i))^(12) + ((20 - 5i)/(7 - 6i))^(12) is real.

Find the value of i^(12)+i^(13)+i^(14)+i^(15)

Show that : i^(101)+i^(102)+i^(103)+i^(104)=0

i+i^(2)+i^(3)+"………"+i^(101)=
