QuestionFind the multiplicative inverse of $-\frac{2 i}{9}$. Choose: a. $\frac{2 i}{9}$, b. $\frac{9}{2 i}$, c. $-\frac{9 i}{2}$, d. $-\frac{9}{2 i}$.

Studdy Solution
implify the expression to get the final answer.
$$2i \times \frac{9}{4} = -\frac{9 i}{2}$$So, the multiplicative inverse of $-\frac{2 i}{9}$ is $-\frac{9 i}{2}$, which corresponds to option C.
