Question 1.The value of √(-16) is(a) -4i(b) 4i(c) -2i(d) 2i, Answer: (b) 4iHint:Given, √(-16) = √(16) × √(-1)= 4i {since i = √(-1) }, Question 2.The value of √(-144) is(a) 12i(b) -12i(c) ±12i(d) None of these, Answer: (a) 12iHint:Given, √(-144) = √{(-1) × 144}= √(-1) × √(144)= i × 12 {Since √(-1) = i}= 12iSo, √(-144) = 12i, Question 3:The value of √(-25) + 3√(-4) + 2√(-9) is(a) 13i(b) -13i(c) 17i(d) -17i, Answer: (c) 17iHint:Given, √(-25) + 3√(-4) + 2√(-9)= √{(-1) × (25)} + 3√{(-1) × 4} + 2√{(-1) × 9}= √(-1) × √(25) + 3{√(-1) × √4} + 2{√(-1) × √9}= 5i + 3×2i + 2×3i {since √(-1) = i}= 5i + 6i + 6i= 17iSo, √(-25) + 3√(-4) + 2√(-9) = 17i, Question 4.if z lies on |z| = 1, then 2/z lies on(a) a circle(b) an ellipse(c) a straight line(d) a parabola. (1 – w + w²)×(1 – w² + w4)×(1 – w4 + w8) × …………… to 2n factors is equal to(a) 2n(b) 22n(c) 23n(d) 24n, Answer: (b) 22nHint:Given, (1 – w + w²)×(1 – w² + w4)×(1 – w4 + w8) × …………… to 2n factors= (1 – w + w2)×(1 – w2 + w )×(1 – w + w2) × …………… to 2n factors{Since w4 = w, w8 = w2}= (-2w) × (-2w²) × (-2w) × (-2w²)× …………… to 2n factors= (2² w³)×(2² w³)×(2² w³) …………… to 2n factors= (2²)n {since w³ = 1}= 22n, Question 20.The modulus of 5 + 4i is(a) 41(b) -41(c) √41(d) -√41, Answer: (c) √41Hint:Let Z = 5 + 4iNow modulus of Z is calculated as|Z| = √(5² + 4²)⇒ |Z| = √(25 + 16)⇒ |Z| = √41So, the modulus of 5 + 4i is √41.
