Question

express the following in a+ib form (-i) (2i) (-1/8i)^3​

Answer 1

Answer:

$- i \times 2i \times (\frac{ - i}{8})^{3} \\ \\ 2 \times ({ - i})^{2} \times \frac{ ({ - i})^{3} }{( {8)}^{3} } \\ \\ 2 \times 1 \times \frac{ - ( - i)}{512} \\ \\ 2 \times \frac{i}{512} \\ \frac{i}{256} \\ \\ 0 + \frac{i}{256}$
