Q
Q: What is the value of 5! (5 factorial)?
Solution:
5! = 5 * 4 * 3 * 2 * 1 = 120.
Steps: 8
Show Steps
Step 1: Understand what '5!' means. The '!' symbol means 'factorial'.
Step 2: To find 5!, you need to multiply all whole numbers from 5 down to 1.
Step 3: Start with the number 5.
Step 4: Multiply 5 by the next lower number, which is 4. So, 5 * 4 = 20.
Step 5: Now take the result (20) and multiply it by the next lower number, which is 3. So, 20 * 3 = 60.
Step 6: Next, take the result (60) and multiply it by the next lower number, which is 2. So, 60 * 2 = 120.
Step 7: Finally, take the result (120) and multiply it by 1. So, 120 * 1 = 120.
Step 8: The final result is 120, so 5! = 120.
