Answer :
Answer:
10
Step-by-step explanation:
The factorial of a number is the product of all positive integers less than or equal to that number. In this case, we are given that p! = 2×10⁸. The only integer that satisfies this equation is 10, because 10! = 10×9×8×7×6×5×4×3×2×1 = 2×10⁸. Therefore, p = 10.
