i^(i8)-3i^(7)+i^(2)(1+i^(4))(-i)^(26)

Simplifiy i^(18)-3.i+i^(2)(1+i^(4))(-i)^(26)

Simplify i^18-3i^7 +i^2 (1 +i^4) (-i)^26 .

Find the value of (i^(6)+i^(7)+i^(8)+i^(9))/(i^(2)+i^(3))

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

If (i^(4)+i^(9)+i^(26))/(2-i^(8)+i^(10)-i^(15))=A+i B then (A, B)=

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)

(-i)(2i)(-(1)/(8)i)^(3)

Prove that: (i) (1-i)^(2)=-2i (ii) (1+i)^(4)xx(1+(1)/(i))^(4)=16 (iii) {i^(19)+((1)/(i))^(25)}^(2)=-4 (iv) i^(4n)+i^(4n+1)+i^(4n+2)+i^(4n+3)=0 (v) 2i^(2)+6i^(3)+3i^(16)-6i^(19)+4i^(25)=1+4i .
