Problem
Evaluate the expression. If the answer is not an integer, round to four decimal places. $9 !$ Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The value is not an integer, $9 !=\square$. (Round to four decimal places as needed.) B. The value is an integer, $9 !=\square$. (Type an integer.)
Solution
Step 1 ：The expression \(9 !\) represents 9 factorial, which is the product of all positive integers from 1 to 9.
Step 2 ：So, \(9 ! = 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1 = 362,880\).
Step 3 ：\(\boxed{362,880}\) is the final answer.
