Question

-3i and 3i are ..... Of each other? a. Additive inverses B. Conjugates C. Both D. N. O.

Answer 1

B. Conjugates

Explanation:

`a+bi` and `a-bi`, where`a` and `b` are real numbers, are conjugate of each other

and if `a=0`, `bi` and `-bi` are conjugate of each other and hence so are `-3i` and `3i`.
