To find the value of 4p2 when p is equal to 8, we can follow these steps:
- First, substitute the value of p into the equation: 4p2.
- This gives us: 4 * (82).
- Calculate the exponent: 82 = 64.
- Now, substitute back into the equation: 4 * 64.
- Finally, multiply to get the result: 4 * 64 = 256.
Therefore, the value of 4p2 when p = 8 is 256.
