Multiple choice general knowledge math & puzzles The conjugate of a complex number is 1/i-1. Then the complex number is -1/i-1 1/i+1 1/i-1 -1/i+1 Reveal answer Fill a bubble to check yourself D Correct answer Explanation The conjugate of z is 1/(i-1). To find z, take the conjugate of the conjugate: conj(1/(-1+i)) = 1/(-1-i). This can be written as -1/(1+i). Option 346060 matches this form.
