1+i^(2)+i^(4)+i^(6)

i^(2)+ i^(4) +i^(6) +……" upto " (2k + 1) terms , k in N is :

Evaluate: (i^(2)+i^(4)+i^(6)+i^(7))/(1+i^(2)+i^(3))

The value of i^(2)+i^(4)+i^(6)+i^(8)... upto (2n+1) terms,where i^(2)=-1, is equal to:

If n is an odd positive integer then the value of (1+ i^(2n) + i^(4n) + i^(6n) ) ?

1 + i^(2n) + i^(4n) + i^(6n)

Evaluate 2i^(2)+ 6i^(3)+3i^(16) -6i^(19) + 4i^(25)

Evaluate 2i^(2)+ 6i^(3)+3i^(16) -6i^(19) + 4i^(25)

Write the following in the form x+iy: (i) (3+2i)(2-i) (ii) 2i^(2)+6i^(3)+3i^(16)-6i^(19)+4i^(25) . (iii) ((3-2i)(2+3i))/((1+2i)(2-i)) .

The value of (i^(5)+i^(6)+i^(7)+i^(8)+i^(9))/(1+i) is (1)/(2)(1+i)(b)(1)/(2)(1-i)(c)1(d)(1)/(2)
