Answer 1

Resposta:

$\frac{6 + i}{ - 3i} = \\ \\ \frac{6 + i}{ - 3i} \times \frac{i}{i} \\ \\ \frac{(6 + i) \times i}{ - 3i \times i} \\ \\ \frac{6i + {i}^{2} }{ - 3 {i}^{2} } \\ \\ \frac{6i - 1}{ - 3i \times ( - 1)} \\ \\ \frac{6i - 1}{3} \\ \\ - \frac{1}{3} + \frac{6}{3} i \\ \\ = - \frac{1}{3} + 2i$
