Final answer:
The image point (8,-6) is transformed on the x-axis by d⁵, resulting in the new coordinates of (40,-6).
Step-by-step explanation:
When the point (8,-6) is transformed on the x-axis by d⁵, the x-coordinate is multiplied by a power of 5. In this case, the new x-coordinate will be 8 * 5 = 40. The y-coordinate remains the same, so the image point after the transformation is (40,-6).
