Final answer:
To find the value of p^2 + 4 when p=3, square p to get 9, and then add 4 to get 13. So the answer is 13.
Step-by-step explanation:
The student asks, "What is the value p2 +4 when p=3?" To solve this, perform the calculation using the given value of p:
- p2 means p times p, which is 3 times 3.
- 3 times 3 equals 9.
- Add 4 to this result: 9 + 4 equals 13.
Therefore, the value of p2 +4 when p=3 is 13.
