Final answer:
This mathematics question appears to involve vectors, the plotting of points, and the relationships between electric charges and distance. The student may be asked to analyze points, perform vector operations, and apply principles of physics related to charges.
Step-by-step explanation:
The student is asking a question related to a mathematical concept, possibly involving coordinates, vectors, or physics-related calculations about electric potential. The points P''(-1,3), Q''(-4,2), R''(-2,5) appear to be coordinates in a 2D space which could be used for plotting points, finding distances, or calculating the slope between points.
The inclusion of symbols like â, ī, ®, and square root signs suggests that the concepts of vector addition, subtraction, and magnitudes are involved, as well as some trigonometry for determining angles. Moreover, the question seems to be about establishing relationships between charges and distances, as inferred from the provided ratios and square law principles (e.g., qr| d² = qs| D²).
The complete question is: How can I prove that (p→q)∧(p→r) ⇔ p→(q∧r)
