Question

The imaginary part of 3 + 2 - 54 1 2 - 3 - 2 - 54 1 2 ,can be, - 6, - 2 6, 6, 6

MARKS App · Accepted Answer

| 3 + 2 - 54 | = 9 + 216 = 15 3 + 2 - 54 1 / 2 = ± 15 + 3 2 + i 15 - 3 2 = ± 3 + i 6 Also 3 - 2 - 54 1 / 2 = ± 3 - i 6 Hence 3 + 2 - 54 1 / 2 - 3 - 2 - 54 1 / 2 = ± 2 6 i or ± 6 Hence, imaginary part = ± 2 6
