Problem
Divide the following complex numbers: \( \frac{2+i}{3-2 i} \) Select one: \( \frac{4+7 i}{13} \) \( \frac{8+7 i}{13} \) \( \frac{4+7 i}{5} \) \( \frac{8+7 i}{5} \)
Solution
Step 1 ：\(\frac{2+i}{3-2i} \cdot \frac{3+2i}{3+2i}\)
Step 2 ：\(\frac{(2+i)(3+2i)}{(3-2i)(3+2i)}\)
Step 3 ：\(\frac{4+7i}{13}\)
