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

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

Evaluate [ i^(14) - (1/i)^(34)]^2

Evaluate : (i^(18)+((1)/(i))^(25))

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

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

Evaluate: (i) .^(12)C_(1)+.^(12)C_(2)+.^(12)C_(3)+ . . .+.^(12)C_(12) (ii) .^(19)C_(3)+.^(19)C_(5)+.^(19)C_(7)+ . . .+^(19)C_(19) .

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

Evaluate: " "(i)" "i^(19)" "(ii)" "i^(62)" "(iii)" "i^(373)

Evaluate 1+i+i^2+i^3
