Find the distance between the points 6 + 5i and 1 – 2i.

Treat each complex number as a point in the plane: 6 + 5i is (6, 5), and 1 − 2i is (1, −2). The horizontal difference is 6 − 1 = 5, and the vertical difference is 5 − (−2) = 7. By the distance formula, the distance is √(5² + 7²) = √74 ≈ 8.6, so the answer is approximately 8.6.
