Evaluate: [i^(19)+((1)/(i))^(25)]^(2)

Find the values of [i^18+(1/i)^25]^3

Evaluate: quad [i^(18)+((1)/(i))^(25)]^(3)

Evaluate : (i) i^(135) (ii) i^((1)/(47) (iii) (-sqrt(-1))^(4n +3) , n in N (iv) sqrt(-25) + 3sqrt(-4) + 2 sqrt(-9)

Express the following in the standard form a + ib: (i^(18)+((1)/(i))^(25))^(3)

Evaluate (i^17-1/i^34)^3 .

Simplify the following : (i) [i^(19) +(1)/(i^(25))]^(2) (ii) [i^(5)- (1)/(i^(3))]^(4)

Show that: {i^(19)+((1)/(i))^(25)}^(2)=-4( ii) {i^(17)-((1)/(i))^(34)}^(2)=2i (iii) {i^(18)+((1)/(i))^(24)}^(3)=0 (iv) i^(n)+i^(n+1)+i^(n+2)+i^(n+3)=0 for all n in N.

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

Find the value of (1+i)^(3)+(1-i)^(6)
